Question: Suppose x is a binomial random variable with p = .4 and n = 25. a. Would it be appropriate to approximate the probability distribution

Suppose x is a binomial random variable with p = .4 and n = 25.
a. Would it be appropriate to approximate the probability of x with a normal Explain.
b. Assuming that a normal provides an adequate approximation to the of x, what are the mean and variance of the approximating normal Use Table I in Appendix D to find the exact value of P(x ≥ 9).
d. Use the normal approximation to find P(x ≥ 9).
