Suppose x is a binomial random variable with p = .4 and n = 25. a. Would

Question:

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). Distribution
The 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...
