**I AM RESUBMITTING THIS QUESTION. I NEED THE FIRST THREE QUESTIONS ANSWERED. **

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 less 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.

8, 7, 7, 5, 5, 5, 8, 9, 7, 8, 5, 6

What can be concluded at the the αα = 0.05 level of significance level of significance?

- For this study, we should use Select an answer t-test for a population mean z-test for a population proportion
- The null and alternative hypotheses would be:

H0:H0: ? p μ Select an answer < ≠ > =

H1:H1: ? μ p Select an answer < > = ≠

- The test statistic ? t z = (please show your answer to 3 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
- The p-value is ? > ≤ αα
- Based on this, we should Select an answer accept fail to reject reject the null hypothesis.
- Thus, the final conclusion is that ...
- The data suggest the populaton mean is
**significantly**less than 8 at αα = 0.05, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is less than 8. - The data suggest that the population mean wait time for men who wear a tie is not
**significantly**less than 8 at αα = 0.05, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is less than 8. - The data suggest the population mean is not
**significantly**less than 8 at αα = 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.

- The data suggest the populaton mean is
