# Question

These statistics were calculated from two random samples:

p̂1 = .60 n1 = 225 p̂2 = .55 n2 = 225

a. Calculate the p-value of a test to determine whether there is evidence to infer that the population proportions differ.

b. Repeat part (a) with p̂1 = .95 and p̂2 = .90.

c. Describe the effect on the p-value of increasing the sample proportions.

d. Repeat part (a) with p̂1 = .10 and p̂2 = .05.

e. Describe the effect on the p-value of decreasing the sample proportions.
