Chapter 17, Problem 59E

Suppose that a random sample of n=7056 adults is to be chosen for a survey. Assume that the gender of each adult in the sample is equally likely to be male as it is female. Estimate the probability that

a. the number of females in the sample is between 3486 and 3570.

b. the number of female in the sample is less than 3486.

c. the percentage of females in the sample is below 50.6%. (Hint: Find 50.6% of 7056 first.)
