Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
(a) Suppose n = 27 and p = 0.40. (For each answer, enter a number. Use 2 decimal places.)
n.p =
n.q =
Can we approximate p by a normal distribution? Why? (Fill in the blank. There are four answer blanks. A blank is represented by

What are the values of u, and o,? (For each answer, enter a number. Use 3 decimal places. )
(b) Suppose n = 25 and p = 0.15. Can we safely approximate p by a normal distribution? Why or why not? (Fill in the blank. There are four answer blanks. A blank is represented by
