Question:

Basic Computation: pˆ 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 5 33 and p 5 0.21. Can we approximate the pˆ distribution by a normal distribution? Why? What are the values of p mˆ and p s ˆ?

(b) Suppose n 5 25 and p 5 0.15. Can we safely approximate the pˆ distribution by a normal distribution? Why or why not?

(c) Suppose n 5 48 and p 5 0.15. Can we approximate the pˆ distribution by a normal distribution? Why? What are the values of p mˆ and p s ˆ?
