In the library on a university campus, there is a sign in the elevator that indicates a limit of 16 persons. Further more, there is a weight limit of 2500 pounds. Assume the average weight of students, faculty and staff on campus is 150 pounds, the standard devaiton is 27 pounds and that the distribution is approximately normal, If a random sample of 16 persons from the campus is taken. What is the standard deviation of the sampling distribution
Are you talking about the standard error of the mean (SEm)?
SEm = SD/√n
