basis of the survey,

BusinessWeek conducted a survey of graduates from 30 top MBA programs ( Business Week, September 22, 2003). On the basis of the survey, assume that the mean annual salary for male and female graduates 10 years after graduation is $168,000 and $117.000. respectively. Assume the standard deviation for the male graduates is 540.000. and for the female graduates it is 525.000.

a. What is the probability that a simple random sample of 40 male graduates will provide a sample mean within $10,000 of the population mean, $168,000?

b. What is the probability that a simple random sample of 40 female graduates will provide a sample mean within 510.000 of the population mean. $117.000?

c. In which of the preceding two cases, part (a) or part (b). do we have a higher probability of obtaining a sample estimate within $10,000 of the population mean? Why?

d. What is the probability that a simple random sample of 100 male graduates will provide a sample mean more than $4000 below the population mean?
