Assignment: Data Analysis and Hypothesis Testing
Please use Excel to do the exercises listed below. Create the Excel outputs into a single Excel file.Also, create a tab separately for each (sub). Clearly name each tab, for instance “Q1_a” or “Q2b”.
Please access the “Carrier Dome Data” do the following.
1. Basic Data Analysis (in the Excel tab, procedures and results should all be included and easily observable)
(a) Create Cross-tabulation table of the following, (Use Pivot table function)
- Gender(X1) vs. Year in School (X2) vs. Commute method (X5)
- Gender(X1) vs. Interest in Exercise (X8a)
(b) Find the Means and Standard deviations of the variables X8a, X8c, X8g, and X8l.
(c) Find the Correlations of X8a, X8c, X8g, and X8l.
2. Hypothesis Testing(in the Excel tab, the variables used, procedure of testing, and the resultsshould all be included and clearly observable)
(a) Test the null hypothesis that the mean of X8c is same for men and women. Using the P value, can you reject H0 at a 95% level of confidence?
(b) Test the null hypothesis that the mean of X8l does not exceed the mean of X8g. Using the P value, can you reject H0 at a 95% level of confidence?
(c) Test the null hypothesis that the mean of X8l does not exceed the mean of X8g by more than 0.8. Using the P value, can you reject H0 at a 95% level of confidence?
3. Create Two New Hypothesis (on your own) and Test at the 95% level of confidence, using the given data. The hypothesis should be about gender difference. For example, see Question 2 (a).
(In the Excel tab, exact hypothesis, the variables used, and the resultsshould all be included and clearly observable)
(a) Hypothesis #1: _______________________________________________
(b) Hypothesis #2: _______________________________________________
