Let y be a binomial random variable with n = 10 and n= 0 .5.
a. Calculate P (4 ≤ y ≤ 6) .
b. Use a normal approximation without the continuity correction to calculate the
same probability. Compare your results. How well did the normal
approximation work?
c. Use a normal approximation with the continuity correction to calculate the
same probability. Compare your results. Does the continuity correction help?
