Statistics project

In this project you will utilize some of the statistical concepts we studied in class to analyze some data. The project will make use of Excel or a calculator with built-in statistical functions. You will be given a set of data to analyze. Your data consists of poll results for a two-candidate election. You should set up a hypothesis test to test the claim that candidate A will receive greater than 50% of the population vote (so p>0.50). Your sample size is 100. Your data consists of 1’s and 0’s. A 1 represents a yes vote for candidate A in the sample. You should specify the null hypothesis and the alternate hypothesis. You should test the null hypothesis and compute the corresponding P-value using both

1) the traditional approach where you compute Z and also

2) the exact binomial distribution.

The significance level is 0.05. Make sure your data meets any requirements necessary in order to use the normal approximation in computing Z.

Your report should consist of the following:

 A cover page where you include your name and assigned class number.

 An Introduction where you state the task your report addresses.

 An Analysis section where you show the hypothesis and formulas for both parts of the project.

 A Results section where you show your results for both parts of the project.

 A Conclusions section where you state your conclusions for both parts of the project.

 An appendix where you include your raw data.

You should email me the actual Excel workbook you used in this project. If you use a calculator you must include in an appendix of your report detailed descriptions of the functions you used and how you used them including any parameters you had to input to the functions. You must use built-in statistical functions on your calculator or Excel for your analysis. No credit will be given for answers obtained via plugging into formulas. However, you should show all formulas that would be required if you could not use technology for this project.

Note: This project is to be an individual effort. You should type up your report using a word processor (such as Microsoft Word). You are not to consult with other students or anyone else (except the professor) on any aspect of the project. You may ask your professor any questions you have. Your report should be either typed or very neatly hand printed on single-sided white paper with a staple in the upper left-hand corner. Do not put your report in any kind of binder.
