A public bus company official claims that the mean waiting time for Bus # 14 during peak hours is approximately 10 minutes. Karen took Bus # 14 during peak hours on 36 different occasions. Her mean waiting time was 8.7 minutes. Assume that the population standard deviation o of 2.9 minutes is known. At the 0.01 significance level, test if the mean of all the peak hours waiting time for Bus # 14 is significantly different from 10 minutes. Part I. Which of the following is the appropriate set of null and alternative hypotheses? [Select] - A. Ho : μ = 8.7 vs Ha : μ # 8.7 B. Ho X = 8.7 vs H₁ : X : 8.7 X = 10 vs H₂ : X C. Ho D. Ho = 10 vs Ha: 10 10 Part II. What is the computed value of the test statistic Part III. What conclusion may be drawn? [Select] ✓ [Select] -2.6897 2.6897 -2.6789 2.9867 W. There is sufficient evidence to reject Ho. The mean peak hours waiting time for Bus # 14 does not differ significantly from the hypothesized mean waiting time. X. There is insufficient evidence to reject Ho. The mean peak hours waiting time for Bus # 14 does not differ significantly from the hypothesized mean waiting time. Y. There is sufficient evidence to reject Ho. The mean peak hours waiting time for Bus # 14 differs significantly from the hypothesized mean waiting time. Z. There is insufficient evidence to reject Ho. The mean peak hours waiting time for Bus # 14 differs significantly from the hypothesized mean waiting time. MacBook Air
