The average wait time to get seated at a popular restaurant in the city on a Friday night is 8 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. 7, 8, 8, 8, 9, 9, 8, 6, 6, 8, 8, 6, 9, 8, 9 What can be concluded at the the a = 0.05 level of significance level of significance? 0 a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: :1 :1 H0: ? 0 Select an answer 0 H1: ? G Select an answer O c. The test statistic ? c = [:] (please show your answer to 3 decimal places.) d. The p-value = C] (Please show your answer to 4 decimal places.) e. The p-value is ? c o: f. Based on this, we should Select an answer 0 the null hypothesis. g. Thus, the final conclusion is that O The data suggest the populaton mean is significantly different from 8 at a = 0.05, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is different from 8. O The data suggest the population mean is not significantly different from 8 at o: = 0.05, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is equal to 8. O The data suggest that the population mean wait time for men who wear a tie is not significantly different from 8 at oz = 0.05, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is different from 8
