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 greater for men who wear a tie? Wait times for 12 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 9, 5, 5, 7, 8, 5, 7, 7, 9, 5, 6, 9 What can be concluded at the the a = 0.10 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 Select an answe c. The test statistic tv (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 a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 7 at a = 0.10, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is more than 7. The data suggest the population mean is not significantly more than 7 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 7. O The data suggest that the population mean wait time for men who wear a tie is not significantly more than 7 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 more than 7.

For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: P Select an answer H1: pv Select an answer v c. The test statistic (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 f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ..
