A survey of first-year and second-year students at a large university asked if students were satisfied with college life. We are interested in whether there is a difference between first and second-year students with respect to this question. You performed a hypothesis test and found there was no evidence of a difference between first and second-year students in response to this question. You based this conclusion on a test using alpha = 0.01. Would you have made the same decision at alpha = 0.05? Explain. (Hint: state the null and alternative hypotheses).

In a survey of a SRS of 463 first-year college students the students were asked about studying habits. Among these students the mean response of studying time was 15.3 hours. Suppose we know that study time among similar students varies with standard deviation 8.5 hours. Does this study give statistically significant evidence at the 0.05 significance level that students generally claim to study more than 15 hours per week on average?  For full credit, perform a complete significance test (that is,...
