For this project, you will be gathering quantitative data from two groups in order to make inferences about the populations from which these groups come from. After you gather your data, you will describe each variable separately. Then, you will perform a two-sample t-test or two-sample z test, depending on the kind of data you have collected.

Idea Which I would like to talk about

• Do college males sleep a different number of hours each night than college females?

(Use any data you can find for the Idea so that I can understand it and do it again with the data I collect)

Write in the format of

1. Introduction - Talk about your project idea, how you came up with the idea, what your null and alternative hypotheses are (e.g.., do you think one group will have a greater mean than another, or do you simply think the groups will be different?), and how you gathered your data.

2. Describing your groups

Compute summary statistics for each group and discuss what the graphs and summary statistics tell you about the two groups. Talk about any similarities and differences you detect between the groups

3. Conduct a two-sample t-test or z-test

Conduct the two-sample t-test or the paired t-test. Write out your null and alternative hypotheses. Talk about the results of your hypothesis test. What was the p-value? Interpret the p-value in your own words. Based on the results of the hypothesis test, do you reject or fail to reject Ho?

4. Conclusion and Summary

Briefly summarize what you did for this project and what you found. Discuss any shortcoming of the methods you used to gather data. Did you discover anything that surprised you when you analyzed the data? Do you think the results would have been different if you had bigger sample sizes? If you had to do the project again, how would you do it differently?
