Question
The average wait time to get seated at a popular restaurant in the city on a Friday night is 13 minutes. Is the
mean wait time different 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.
12, 11, 14, 13, 14, 11, 13, 12, 13, 13, 11, 12
What can be concluded at the the a = 0.01 level of significance level of significance?
a. For this study, we should use
b. The null and alternative hypotheses would be:

e. The p-value is
?
f. Based on this, we should
O the null hypothesis.
Select an answer
g. Thus, the final conclusion is that ...
The data suggest the populaton mean is significantly different from 13 at a = 0.01, so there is
statistically significant evidence to conclude that the population mean wait time for men who
wear a tie is different from 13.
The data suggest the population mean is not significantly different from 13 at a = 0.01, so there
is statistically insignificant evidence to conclude that the population mean wait time for men who
wear a tie is equal to 13.
The data suggest that the population mean wait time for men who wear a tie is not significantly
different from 13 at a = 0.01, so there is statistically insignificant evidence to conclude that the
population mean wait time for men who wear a tie is different from 13.
