The average wait time to get seated at a popular restaurant in the city on a Friday night is 7 minutes. Is the mean wait time different 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. 7, 5, 8, 5, 6, 6, 6, 9, 8, 9, 7, 5, 9 What can be concluded at the the a = 0.05 level of significance level of significance? %3D a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? 0 Select an answer e H1: ? 0 Select an answer e c. The test statistic ? 8 (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 ?. e a f. Based on this, we should Select an answer e the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population mean is not significantly different from 7 at a = 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 7. %3! O The data suggest the populaton mean is significantly different from 7 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 7. O The data suggest that the population mean wait time for men who wear a tie is not significantly different from 7 at a = 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 7. %3!

For this study, we should use b. The null and alternative hypotheses would be: Select an answer Но: Select an answer H1: Select an answer O c. The test statistic ? 0 (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 ?. e a f. Based on this, we should select an answer 6 the null hypothesis. g. Thus, the final conclusion is that ...
