- Suppose the commuting time on a particular train is uniformly distributed between 34 and 54 minutes. What is the mean commuting time?The average wait time to get seated at a popular restaurant in the city on a Friday night is 15 minutes. Is the mean wait time different for men who wear a tie? Wait times for 15 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 13, 13, 14, 13, 17, 16, 17, 17, 13, 14, 15, 14, 16, 15, 14 What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v Select an answer v H1: Select an answer v c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population mean is not significantly different from 15 at a = 0.10, so there is statistically insignificant…The average final exam score for the statistics course is 74%.
