Group Spending Comparison Between British, German, French, And Italian ConsumersFrom the results, we conclude that the Germans, French, and Italians outspend the British in groups, but that the variance is higher amongst Germans. This is shown by the higher upper limit amongst Germans as compared to others. Germans have the highest standard deviation and standard error, which shows that there is more variance than amongst other nationalities. Since the means fall near the median, we can say that our sample of mean are true.

Comments: The French and Italians have the highest mean, while the British and the Germans are close together in with a lower spending per person. The variances, however, between the British and the Germans are much higher for the Germans, indicating that there may be a subset of higher spenders. The same is true for the French, which could mean a skew on the higher or lower spending range. This difference between Germans and Brits is supported by the higher limit number for Germans. The French and Italians seem to uniformly spend more, as evidenced by their mid-sized SD and relatively high lower limit and relatively low upper limit. The sample data from the Germans is higher, as shown by the higher standard deviation.

Comments: The above results demonstrate that the Z-score values are above SD for all but FI, BI, BF and BG. For these, the null hypothesis is not proven, for all others the null hypothesis is accepted at a 95% confidence limit.
Task 1(e) - Regression
Comments: Above result of regression shows that if none of the nationality go to the holiday so the expenditure for the respective family will be 515.80,550.69,545.70 and 617.42 for respective nationalities as given in the table. And if they go to the holiday so the expenditure to a large extend will be influenced by the slope of the regression equation.
Task 1(f) - Correlation
Comments: As R-square coefficient shows that,71%, 71%, 66% and 67% of the variation may be predicted by change in actual family size, for respective nationalities and the rest of the percentage i.e,29%, 29%, 34% and 33% are unpredicted. The value of the T-statistics of intercept and slope, indicates that they cannot be zero, and for the each nationality the regression equation can be used for the prediction.
Task 1(g) - Estimate for the spending of a family of five
British

Italian
Estimate
Comments: The results indicate that if no one goes on holiday the highest family expenditure is for the Italians. If someone goes on holiday, the highest expenditure is bound to be the Italians, because their slope is higher than other nationalities.
Task 1(h) - Difference of opinions within nationalities
Comments: For all nationalities Italians the chi-square value lies under the 5% degree of freedom, therefore there exists a relationship in the opinion of the nationalities. But the value of chi-square is not in the degree of freedom limit, so there is exists no relationship in opinions with the nationality.

BACKGROUND INFORMATION
Erehwon is an island in the Mediterranean. Like many similar islands Erehwon is a tourist destination. The island is quite small, approximately 20 kilometers north to south by about 5 kilometers east to west. There are three main towns on the island, Erehwon Town, Lazzeville and Brashville (see appendix for a map). There are a large number of small villages scattered over the island.
Erehwon Town is the capital of the island and the only port on the island. The town is the commercial centre of the island with all the local government administrative offices based there. The port provides a focus for the small ship repair industry and is the main link with the outside world. Around the port area are a number of light engineering businesses, several food processing plants and a winery. Virtually all tourists pass through the port as there is no airport but very few actually stay in Erehwon Town.
Lazzeville used to be a fishing port but the tourist trade has since taken over the town. This has reduced the fishing industry to a fraction of its former size. The fishermen have now turned to running day cruises around the smaller islands around the coast. Despite these changes the *****fishing harbour***** is still a big attraction with the area being the location of many fish restaurants. The nightlife is subdued and focused around restaurants and bars. The restaurants are generally good and the different bars cater for different clientele. As a tourist resort Lazzeville attracts mainly couples over 25 years old and some families. The accommodation is mainly self-catering apartments and studios with several pensions and a few top class hotels. The tourist season runs from April to September.
Brashville is a new resort built around a wide bay at the end of a valley. Its location and prevailing winds make it one of the best places for windsurfing in Europe. There is very little of the original fishing village left, most of the buildings have been turned into accommodation for tourists and no fishing boats operate from the quay now. Here the ex-fishermen operate *****fish picnic***** or *****pirate***** cruises. The restaurants are a mix of fast food outlets and *****international food***** restaurants with a very few good restaurants. The bars are aimed at people under the age of 25 who wish to have a good time. Bars seem to compete on the length of their list of potent cocktails and how late they close. The accommodation is mainly on a room only basis or self-catering, although very few tourists seem to cook anything. The tourists are predominantly young and mainly travelling in single sex groups. The Brashville is marketed as a *****young and lively***** resort. The tourist season runs from May to August.
The infrastructure of the island is quite poor. There is only one major road that runs from Erehwon Town through Lazzieville to Brashville. A network of minor roads connects the scattered villages of the island. The bus service is geared up to take people to work in a morning and bring them back in the afternoon. The vast majority of tourists do not use the buses. Taxis are available but they mainly operate within the towns with only a few willing to undertake journeys beyond their own towns. Those that do, have a reputation for overcharging. Car hire is widely available but expensive and journeys off the main road are not recommended because of the poor quality of the roads.
SPECIFIC INFORMATION
In an attempt to develop the tourist industry of Brashville, Theodoras Spyridos, the head of the Brashville tourist board obtained the results of a survey done of tourists who stayed in Brashville last year. The survey results are contained in appendix 3.
Theodoras would have preferred to have initiated the survey himself but believes the data obtained could be useful if properly an*****d.
APPENDIX 1
APPENDIX 2 - Glossary of Terms Used
Self catering
This is accommodation with cooking facilities and refrigerator. The number of beds varies from two to six. This type of accommodation is aimed at families or groups of friends depending on the type of resort.
Pensions
These are small, family run hotels usually providing bed and breakfast. The number of rooms varies from 5 to 20. Older couples usually take this type of accommodation.
Room only basis
This is when no food or cooking facilities is provided. The accommodation is similar to Pensions in that it is small and usually family run. Young couples who can not be bothered to get up early or cook food usually take this type of accommodation.
Fish picnic
A boat trip to a beach where food is cooked on the beach. Usually a large amount of alcohol is consumed.
Pirate cruise
This is the same as fish picnic without the food but more alcohol.
Young and lively
A resort aimed at young single people who intend to have a good time. A good time usually being defined by the consumption of alcohol and the company of the opposite sex. The nightlife goes on until dawn and breakfast is served in the bars from 10 am until 3 p.m.
International Food
This is food catering to the lowest common denominator of international taste with no reference to the cuisine of the local country. Essentially chips with everything type of meals.

Plagiarism Warning
Summary
*****¢ Plagiarism occurs if you use somebody else's work in an assignment or exam answer, but fail to state where you got the material from.
*****¢ It can happen in any type of assessment where you are given the questions or tasks in advance.
*****¢ If another student uses your work in their answer(s), both you and they will be punished when caught.
*****¢ Punishments for committing plagiarism can be very severe.
*****¢ 25-30 students get caught in the Business school every year.
The details
Plagiarism is a form of cheating in which students use the work of others and present it as their own. The University publishes a fully detailed description of what the term *****˜plagiarism***** means on the University*****s main web-site under the heading *****Procedures for dealing with suspected cases of academic dishonesty. We strongly recommend that you go and read the full document at the above address. Meanwhile, here is an extract of some of the relevant content. You will have committed plagiarism and may be caught, reported and punished (as described below) if you:
*****¢ Copy extensively from the work of others (from sources such as books, magazines, journals, web-sites for example) and submit the work as your own. NB It is acceptable to refer to the work of others as long as you do not use too much, and reference your sources properly. If you do not know how to do this, please follow the guidelines given in the document entitled *****˜Adding quotations and references to your written work***** at this web-site address:
http://www.staffs.ac.uk/schools/business/bsadmin/staff/s3/jamr.htm
*****¢ Copy another students***** work and submit it for assessment under your own name.
*****¢ Allow another student to copy your work and they then submit it for assessment under their name
This last item is of particular importance; few students seem to understand what it means. If, for example, you allow another student to borrow your work and they subsequently copy some that work and present it as their own, you and they will both be punished even though someone else copied your work.
The risks of working with other students
Some assessment tasks are explicitly designed for group work, and it will be made clear that a group answer is expected from you. All other tasks are intended as an assessment of your individual comprehension and performance, and group answers are not permitted. In individually assessed forms of assessment your work must be different from that of every other student. Plagiarism can occur in assignments and any examination where the questions are issued to students in advance. In both cases it is possible for you to ask other people about how best to answer the questions or complete the necessary tasks
You should be aware that different modules and subjects may have different requirements. In some subjects, answers to questions may, for example, require every student on a module to employ or refer to the same diagram(s), concepts and the like in order to construct an acceptable answer. You should note, however, that even in these circumstances your explanations of what the diagrams mean, and any other writing referring to any common diagrams and concepts should all be in your own words. Moreover, the situation may be very different on other modules, where the submission of work that has a very similar structure, or the use of very similar materials such as concepts, diagrams, quotations and the like, to that of another student, may lead to you being accused of plagiarism.
The picture is complicated and, unfortunately, it is not possible to give advice that is directly relevant to every module you study. If you are unsure about how to avoid plagiarism in any specific module, then rather than hoping and guessing, you should ask for guidance from the member of staff who delivers that module.
Our overall advice is straightforward; by all means discuss how best to answer questions or complete tasks with your colleagues, but when it comes to actually writing your answers - DO IT ALONE!
What happens if you get caught?
Contrary to some student rumours, getting caught and being punished for committing plagiarism is not an extremely unusual student offence. The Business School typically uncovers and reports for disciplinary action 25 to 30 students each year for plagiarism
Examination Boards may punish offending students in any manner that they deem fit. Typical punishments Boards may choose range from reducing grades, making students re-sit modules, through to failing students on a module or an entire award. The University regards this form of cheating as a serious offence. Full details of the range of likely punishments can be found on the University*****s web-site under the heading *****Procedures for dealing with suspected cases of academic dishonesty.
Please consider yourself warned!
