Assume that all the distributions are normal, average is always taken to be the arithmetic mean \(\bar{x}\) or \(\mu\). A college Physical Education Department offered an Advanced First Air course last semester. The scores on the comprehensive final exam were normally distributed, and the the z scores for some of the students are shown below:

Robert, 1.10

Juan, 1.70

Susan, -2.00

Joel, 0.00

Jan, -0.80

Linda,1.60

Which of these students scored below the mean?

Distribution Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
(a) Suppose \(n = 100\) and \(p= 0.23\). Can we safely approximate the \(\hat{p}\) distribution by a normal distribution? Why?
Compute \(\mu_{\hat{p}}\) and \(\sigma_{\hat{p}}\).
