Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.(a)
- Suppose n = 26 and
- p = 0.35.
(For each answer, enter a number. Use 2 decimal places.) np = (A)________ nq = (B)________ Can we approximate p by a normal distribution? Why? (Fill in the blank. There are four answer blanks.
