A data set includes data from student evaluations of courses. The summary statistics aren=91, x=3.61, s=0.61. Use a0.05 significance level to test the claim that the population of student course evaluations has a mean equal to3.75.

Assume that a simple random sample has been selected. Identify the null and alternativehypotheses, teststatistic, P-value, and state the final conclusion that addresses the original claim.

What are the null and alternativehypotheses?

A.

H0:

=3.75

H1:

>3.75

B.

H0:

=3.75

H1:

<3.75

Your answer is not correct.

C.

H0:

3.75

H1:

=3.75

D.

H0:

=3.75

H1:

3.75

Part 2

Determine the test statistic. =______

(Round to two decimal places asneeded.)

Part 3

Determine theP-value. =_____

(Round to three decimal places asneeded.)

Part 4

State the final conclusion that addresses the original claim. Reject? Or fail to reject?

H0.

There issufficient? Or not sufficient?

evidence to conclude that the mean of the population of student course evaluations is equal to

3.75is? Or is not?
