For a marketing research it is known that the proportion women who use personal care products is 0.40 and the proportion of men is 0.25 for a sample of 500 women and 400 men chosen at random, who follow a binomial distribution. Calculate the value of the difference between the sample proportion by gender so that the probability is less than 0.9975?

Business weekly conducted a survey of graduates for 30 top MBA programs. On the basis of the survey assume the means annual salary 10 years after graduation is $162,000. Assume the standard deviation is $40,000. Suppose you take a simply random sample of 39 graduates. For a single randomly selected graduate, find the probability that her salary is between $156,692.00 and $161,395.00. For a simple random sample of 39 graduates, find the probability that the average salary is between $156,692.00 and $161,395.00. Is the assumption of normal necessary? Yes, or No.
