(30) Suppose that the number of parking tickets for parking on the street given out on
average in a month is 512.
a. (5) How many parking tickets for parking on the street would you expect to be
written per week assuming that there are four weeks per month?
b. (10) Suppose that we sample 256 weeks and the average number of parking
tickets for parking in the street per week was found to be 130. Use the exact
test to see if we would expect to get more than 512 parking tickets in a month
for parking on the street?
c. (10) Repeat part c using the normal approximation
d. (5) Based on the test results between parts c) and d), do you think that the
normal approximation holds, why or why not?
