Transcribed Image Text:(b) Use technology to find the P-value
P= (Round to three decimal places as needed.)
(c) Decide whether to reject or fail to reject the null hypothesis.
Which of the following is correct?
O A. Reject Ho because the P-value is greater than the significance level
B. Fail to reject Ho because the P-value is greater than the significance level.
O C. Fail to reject Ho because the P-value is less than the significance level.
OD. Reject Ho because the P-value is less than the significance level.
(d) Interpret the decision in the context of the original claim.
OA. At the 5% level of significance, there is sufficient evidence to support the claim that the mean
class size for full-time faculty is more than 31 students.
OC. At the 5% level of significance, there is not sufficient evidence to support the claim that the
mean class size for full-time faculty is more than 31 students.
OB. At the 5% level of significance, there is not sufficient evidence to support the claim that the
mean class size for full-time faculty is fewer than 31 students.
D. At the 5% level of significance, there is sufficient evidence to support the claim that the mean
class size for full-time faculty is fewer than 31 students.
Transcribed Image Text:You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 31 students. You want to test this claim. You randomly select 18 classes taught by
full-time faculty and determine the class size of each. The results are shown in the table below. At a = 0.05, can you support the university's claim? Complete parts (a) through (d) below. Assume the population is
