A data set includes data from student evaluations of courses. The summary statistics are n=88, over bar x=4.15, s =0.67.

Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25.

Assume that a simple random sample has been selected.

1) What are the null and alternative hypotheses, H0 & H1 equation form.

2) What is the t-test statistic? (Round to two decimal places)

3) What is the p value? (Round to three decimal places)

4) State the final conclusion that addresses the original claim. Do we a) reject the H0 hypothesis or b) fail to reject the H0 hypothesis? 5) There is___a) sufficient or b) not sufficient_______ evidence to conclude that the mean of the population of student course evaluations is equal to 4.25____a) is or b) is not___correct.
