The average wait time to get seated at a popular restaurant in the city on a Friday night is 9 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. 10, 8, 6, 8, 10, 7, 10, 7, 7, 7, 7, 8, 8 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 dec mal places.)

The average wait time to get seated at a popular restaurant in the city on a Friday night is 9 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. 10, 8, 6, 8, 10, 7, 10, 7, 7, 7, 7, 8, 8 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: Select an answer ♥ H1: ? v Select an answer v c. The test statistic ? (please show your answer to 3 dec mal places.) d. The p-value (Please show your answer to 4 decimal places.) %3D 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 ... OThe data suggest that the population mean wait time for men who wear a tie is not significantly different from 9 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is different from 9. O The data suggest the populaton mean is significantly different from 9 at a = 0.10, so there is statistically significant evidence to conclude that the population mean wait tíme for men who wear a tie is different from 9. O The data suggest the population mean is not significantly different from 9 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is equal to 9.
