A data set includes data from student evaluations of courses. The summary statistics are

n=87​,
x=3.69​,
s=0.53.

Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 3.75. Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim

a) What are the null and alternative hypotheses?
