A medical journal reported the following frequencies of deaths due to cardiac arrest for each day of the week:

Cardiac Death by Day of the Week
Day                                        F
Monday                                  40
Tuesday                                 17
Wednesday                            16
Thursday                                29
Friday                                    15
Saturday                                 20
Sunday                                   17

We want to determine whether the number of deaths is uniform over the week.
a. Compute the test statistic.
b. Using the p-value approach at 95% confidence, test for the uniformity of death over the week.
c. Using the critical value approach, perform the test for uniformity.
