Please answer B, C, and D

Transcribed Image Text:The average wait time to get seated at a popular
restaurant in the city on a Friday night is 15 minutes. Is
the mean wait time greater for men who wear a tie? Wait
times for 13 randomly selected men who were wearing a
tie are shown below. Assume that the distribution of the
population is normal.
16, 17, 16, 13, 17, 16, 13, 13, 14, 17, 16, 15, 16
What can be concluded at the the a =
0.01 level of
significance level of significance?
a. For this study, we should use
t-test for a population mean

the null
hypothesis.
g. Thus, the final conclusion is that ...
The data suggest the populaton mean is
significantly more than 15 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 more than 15.
%3D
The data suggest that the population mean
wait time for men who wear a tie is not
significantly more than 15 at a = 0.01, so
there is statistically insignificant evidence to
concluge that the population mean wait time
