A data set includes data from student evaluations of courses. The summary statistics are n = 86, x = 3.68, s = 0.69. 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 alternativehypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

A data set includes data from student evaluations of courses. The summary statistics are n
= 86, x = 3.68, s = 0.69. 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 alternativehypotheses, test statistic, P-value, and state the final conclusion that addresses
the original claim.
What are the null and altemative hypotheses?
O A. Ho: u= 3.75
O B. Ho: = 3.75
H: p23.75
H: p> 3.75
O C. Ho: u= 3.75
OD. Ho: u3.75
Hi: με 375
H: u< 3.75
What is the test statistic?
Z =
(Round to two decimal places as needed.)
What is the P-value?
P-value =
(Round to four decimal places as needed.)
State the final conclusion that addresses the original claim.
_( sufficient/not sufficient)
evidence to conclude that the mean of the population of student course evaluations is equal to 3.75
(fail to reject/reject ) HO. There is
– (is/is not) correct.
