Question
A data set includes data from student evaluations of courses. The summary statistics are n= 87, x=4.08, s= 0.58. Use a 0.10 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.
What are the null and alternative hypotheses?
O B. Ho: H= 4.25
H1: µ<4.25
Ο Α. H0 μ#4.25
H1: µ = 4.25
OC. Ho: H= 4.25
H1: µ>4.25
O D. Ho: H= 4.25
H: uz4.25
Determine the test statistic.
(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 Ho. There is
v evidence to conclude that the mean of the population of student course evaluations is equal to 4.25
v correct.
