Question
**Statistical Testing of Classroom Hours Claim** **Scenario:** The dean of a university estimates that the mean number of classroom hours per week for full-time faculty is 11.0 hours. 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 significance level of α = 0.10, can you reject the dean's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. **Data Table:** - 10.4 - 8.2 - 13.1 - 8.8 - 6.1 - 11.3 - 12.6 - 9.9 **Tasks:** **(a) Write the claim mathematically and identify H₀ (null hypothesis) and Hₐ (alternative hypothesis).** Which of the following correctly states H₀ and Hₐ? - **A.** H₀: μ ≤ 11.0 Hₐ: μ > 11.0 - **B.** H₀: μ = 11.0 Hₐ: μ ≠ 11.0 - **C.** H₀: μ ≠ 11.0 Hₐ: μ = 11.0 - **D.** H₀: μ < 11.0 Hₐ: μ ≥ 11.0 - **E.** H₀: μ > 11.0 Hₐ: μ ≤ 11.0 - **F.** H₀: μ = 11.0 Hₐ: μ < 11.0 **(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? - **A.** Fail to reject H₀ because the P-value is greater than the significance level. - **B.** Reject H₀ because the P-value is greater than the significance level. - **C.** Reject H₀ because the P-value is less than the significance level. - **D.**
