Use the binomial distributaccuracy of the normal approximat

binomial distribution. n=20, pi=5

a. Compute the exact probabilities and corresponding normal approximations for y < 5.

b. The normal approximation can be improved slightly by taking P(y ≤ 4.5). Why should this help? Compare your results.

c. Compute the exact probabilities and corresponding normal approximation with the continuity correction for P(8 < y < 14).

Step 1

Given,

Y follows binomial distributon with n = 20, pi = 0.5.

Step 2

**Part ****a). Compute the exact probabilities and corresponding normal approximations for y < 5.**

Step 3

**Part b). The normal approximation can be improved slightly by taking P(y ≤ 4.5). Why should this help? Compare your results.**

This step as known as continuity correction, we use it when continuous probability distribution is being used to approximate a Discrete Probability Distribution. For Example like the same that we are...
