# Question

For each situation in Exercise 7.25, find an interval that contains approximately 95.44 percent of all the possible sample proportions.

In Exercise 7.25

In each of the following cases, find the mean, variance, and standard deviation of the sampling distribution of the sample proportion

a. p =.5, n = 250

b. p =.1, n = 100

c. p =.8, n =400

d. p =.98, n =1,000
