The average wait time to get seated at a popular restaurant in the city on a Friday night is 11 minutes. Is the mean wait time different for men who wear a tie? Wait times for 14 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal.10, 12, 12, 9, 8, 10, 9, 11, 11, 10, 12, 9, 10, 12What can be concluded at the the α = 0.01 level of significance level of significance?For this study, we should use The null and alternative hypotheses would be: H0:H1:The test statistic = (please show your answer to 3 decimal places.)The p-value = (Please show your answer to 4 decimal places.)The p-value is αBased on this, we should the null hypothesis.Thus, the final conclusion is that ... The data suggest that the population mean wait time for men who wear a tie is not significantly different from 11 at α = 0.01, so there is not enough evidence to conclude that the population mean wait time for men who wear a tie is different from 11.The data suggest the populaton mean is significantly different from 11 at α = 0.01, so there is enough evidence to conclude that the population mean wait time for men who wear a tie is different from 11.The data suggest the population mean is not significantly different from 11 at α = 0.01, so there is not enough evidence to conclude that the population mean wait time for men who wear a tie is equal to 11.

10, 12, 12, 9, 8, 10, 9, 11, 11, 10, 12, 9, 10, 12
What can be concluded at the the
α = 0.01 level of significance level of significance?
For this study, we should use
The null and alternative hypotheses would be:
H0:
H1:
The test statistic = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is α
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
The data suggest that the population mean wait time for men who wear a tie is not significantly different from 11 at
α = 0.01, so there is not enough evidence to conclude that the population mean wait time for men who wear a tie is different from 11.
The data suggest the populaton mean is significantly different from 11 at
α = 0.01, so there is enough evidence to conclude that the population mean wait time for men who wear a tie is different from 11.
The data suggest the population mean is not significantly different from 11 at α = 0.01, so there is not enough evidence to conclude that the population mean wait time for men who wear a tie is equal to 11.
