A. For this question you will be deriving statistical conclusions from actual survey data. Follow the steps in order to receive full credit.
• Using the proportional and non-proportional student survey data provided complete the following:
a) 95% confidence interval for the mean with graphical illustrations of standard normal distribution and corresponding Z or T values.
b) One tailed hypothesis test for the mean with corresponding computed and critical values.
c) Two tailed hypothesis test for the mean with corresponding computed and critical values.
d) 95% confidence interval for the standard deviation.
e) Graphical illustration of Chi-Square distribution with critical values.
• You will also do a male vs. female "paired sample test" for one of your two questions (you may assume the population variance is unknown but equal).
