Question 1
An adverse drug effect (ADE) is an unintended injury caused by prescribed medication. The table summarizes the proximal cause of 95 ADEs that resulted from a dosing error at a Boston hospital.
In order to determine whether the true percentages of ADEs in the five "cause" categories differ, a chi-square analysis was conducted. Use the chi-square distribution to determine the rejection region when testing at α = 0.025.

Question 2
A multinomial experiment with
k = 4 cells and
n = 400 produced the data shown in the following table.

Previous studies in this area have shown that
p1 =
p2 =
p3 =
p4 = .25. Construct a 95% confidence interval for the multinomial probability associated with cell 2.
