The Economic Policy Institute periodically issues reports on workers' wages. Suppose the institute reported that mean wages for male college graduates were $37.39 per hour and for female college graduates were $27.83 per hour in 2017. Assume the standard deviation for male graduates is $4.60 and for female graduates it is $4.10. (Round your answers to four decimal places.) What is the probability that a sample of 40 male graduates will provide a sample mean within $1.00 of the population mean, $37.39? What is the probability that a sample of 40 female graduates will provide a sample mean within $1.00 of the population mean, $27.83? Calculate the amount that is $

Question
The Economic Policy Institute periodically issues reports on workers' wages. Suppose the institute reported that mean wages for male college graduates were $37.39 per hour and for female college graduates were $27.83 per hour in 2017. Assume the standard deviation for male graduates is $4.60 and for female graduates it is $4.10. (Round your answers to four decimal places.)
What is the probability that a sample of 40 male graduates will provide a sample mean within $1.00 of the population mean, $37.39?
What is the probability that a sample of 40 female graduates will provide a sample mean within $1.00 of the population mean, $27.83?
Calculate the amount that is $0.60 less than the population mean of $27.83. What is the probability that a sample of 110 female graduates will provide a sample mean less than this amount?
