A data set includes data from student evaluations of courses.
The summary statistics are
n=85​,
x=4.09​,
s=0.55.
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. Identify
the null and alternative​ hypotheses, test​ statistic,
P-value, and state the final conclusion that addresses the original
claim.
