A data set includes data from student evaluations of courses. The summary statistics are n = 90, x=4.19, s= 0.61. Use a 0.05 significance level to test the claim that the population of student 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. What are the null and alternative hypotheses? Test Statistic? P-Value? Reject H0 if the P-value is less than or equal to the significance level a. Fail to reject H0, if the P-value is greater than a.

A data set includes data from student evaluations of courses. The summary statistics are n = 90, x=4.19, s= 0.61. Use a 0.05 significance level to test the claim that the population of student 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.
What are the null and alternative hypotheses?
Test Statistic?
P-Value?
Reject H0 if the P-value is less than or equal to the significance level a. Fail to reject H0, if the P-value is greater than a.
