Suppose that x has a binomial distribution with n = 200 and p = .4.

a. Show that the normal approximation to the binomial can appropriately be used to calculate probabilities about x.

b. Make continuity corrections for each of the following, and then use the normal approximation to the binomial to find each probability:

(1) P(x = 80)

(2) P(x ≤ 95)

(3) P(x < 65)

(4) P(x ≥ 100)

(5) P(x > 100)

DistributionThe word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
