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 = 8.7 vs Ha: 8.7 8.7 C. Ho X = 10 vs Ha: X 10 D. Ho = 10 vs Ha: 10 Part II. What is the computed value of the test statistic? [Select] B. Ho : : X = 8.7 vs Ha: X
