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 5100 and p 5 0.23. Can we safely approximate the pˆ distribution by a normal distribution? Why? Compute p mˆ and p s ˆ .

(b) Suppose n 5 20 and p 5 0.23. Can we safely approximate the pˆ distribution by a normal distribution? Why or why not?
