Please answer B, C, and D 

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 greater for men who wear a tie? Wait times for 13 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 16, 17, 16, 13, 17, 16, 13, 13, 14, 17, 16, 15, 16 What can be concluded at the the a = 0.01 level of significance level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: Select an answer H1: Select an answer c. The test statistic t (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 (? f. Based on this, we should | Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 15 at a = 0.01, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is more than 15. %3D The data suggest that the population mean wait time for men who wear a tie is not significantly more than 15 at a = 0.01, so there is statistically insignificant evidence to concluge that the population mean wait time
