Question:

2.17 Yi, i = 1,

c, n, are i.i.d. Bernoulli random variables with p = 0.6. Let Y denote the sample mean.

a. Use the central limit to compute approximations for i. Pr(Y 7 0.64) when n = 50.

ii. Pr(Y 6 0.56) when n = 200.

b. How large would n need to be to ensure that Pr(0.65 7 Y 7 0.55) = 0.95?

(Hint: Use the central limit theorem to compute an approximate answer.)
