Suppose x is a binomial random variable with p=0.4 and n
=25
(a) Would it be appropriate to approximate the probability
distribution of x with a normal distribution? Explain.
(b)Assuming that a normal distribution provides an adequate
approximation to the distribution of x, what are the mean and
variance of the approximating normal distribution?
(c)Find the exact value of P(x>=9)
(d)Use the normal approximation to find P(x>=9)
