The dean of a university estimates that the mean number of classroom hours per week for full-time faculty is 11.0. As a member of the student council, you want to test this claim. A random sample of the number of classroom hours for eight full-time faculty for one week is shown in the table below. At a = 0.10, can you reject the dean's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 11.4 7.1 13.2 7.6 5.9 11.9 12.1 8.4 O (a) Write the claim mathematically and identify Ho and H. Which of the following correctly states H, and H? O B. Ho: µs11.0 Ha:µ>11.0 O E. Ho: µ>11.0 Hi us11.0 Ο Α. Ho: μ<11.0 H: με 11.0 Ο c. H : μ= 11.0 Ha: u#11.0 O D. Ho: H#11.0 Haiµ =11.0 O F. Ho: µ211.0 Haiu<11.0 (b) Use technology to find the P-value. P= 0.010 (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. Fail to reject H, because the P-value is less than the significance level. O B. Reject H, because the P-value is less than the significance level. OC. Reject H, because the P-value is greater than the significance level. O D. Fail to reject H, because the P-value is greater than the significance level.

Transcribed Image Text:(d) Interpret the decision in the context of the original claim.
A. At the 10% level of significance, there is not sufficient evidence to reject the claim
that the mean number of classroom hours per week for full-time faculty is 11.0.
B. At the 10% level of significance, there is sufficient evidence to reject the claim that
the mean number of classroom hours per week for full-time faculty is 11.0.
C. At the 10% level of significance, there is sufficient evidence to reject the claim that
the mean number of classroom hours per week for full-time faculty is greater than
11.0.
D. At the 10% level of significance, there is not sufficient evidence to reject the claim
that the mean number of classroom hours per week for full-time faculty is less than
11.0.
