Suppose 11% of students are veterans and 142 students are involved in sports. How unusual would it be to have no more than 12 veterans involved in sports? (12 veterans is about 8.4507%) When working with samples of size 142, what is the mean of the sampling distribution for the proportion of veterans? When working with samples of size 142, what is the standard error of the sampling distribution for the proportion of veterans? Compute P(ˆp≤p^≤ 0.084507).
