The data suggest the populaton mean is significantly less than 10 at α = 0.10, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is less than 10.

Question

The average wait time to get seated at a popular restaurant in the city on a Friday night is 10 minutes. Is the mean wait time less for men who wear a tie? Wait times for 15 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal.

7, 10, 11, 9, 11, 7, 8, 11, 9, 9, 11, 9, 11, 9, 7

What can be concluded at the the α

= 0.10 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

Based on this, we should
the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population mean is not significantly less than 10 at α
= 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 10.
The data suggest that the population mean wait time for men who wear a tie is not significantly less than 10 at α
= 0.10, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is less than 10.
The data suggest the populaton mean is significantly less than 10 at α
