The Office of Student Services at UNC would like to estimate the proportion of UNC's 34,000 students who are foreign students. In their random sample of 50 students, 4 are foreign students. Unknown to them, the proportion of all UNC students that are foreign students is 0.061. For each student, let x=0 if the student is from the U. S.
Find the mean and the standard deviation of the sampling distribution of the sample proportion for a sample of size 50.
