Transcribed Image Text:A data set includes data from student evaluations of courses. The summary statistics are n=92, x = 3.43, s= 0.67. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 3.50.
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 altemative hypotheses?
O A. Ho:3.50
O B. Ho: H#3.50
H: u3.50
H:u=3.50
OC. Ho: H=3.50
OD. Ho: H=3.50
H,:u<3.50
H: u>3.50
Determine the test statistic.
O (Round to two decimal places as needed.)
Determine the P-value.
(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
V Họ. There is
V evidence to conclude that the mean of the population of student course evaluations is equal to 3.50
v correct
