b) If we use a 0.01 significance level, what is the critical value for the test?
c) Calculate the value of the test statistic.
d) What is your decision about the null hypothesis and your conclusion about usher’s claim?
e) Calculate the p-value for this test.

Customers arrive at a movie theater at the advertised movie time
only to find that they have to sit through several previews and
prepreview ads before the movie starts. Many complain that the time
devoted to previews is too long. A preliminary sample conducted by
The Wall Street Journal showed that the standard deviation of the
amount of time devoted to previews was four minutes. Use that as a
planning value for the standard deviation in answering the
following questions....

QuadPlex Cinema is the only movie theater in Idaho Falls. The

the manager of the movie theater made the following suggestions:
“Since QuadPlex is a local monopoly, we should just increase ticket
