Quizplus · Accepted Answer

When approximating a binomial distribution with a normal distribution for a binomial random variable X with a very large n, we use the continuity correction factor. To approximate P(X ≤ 5), we use 5.5 as the cutoff point on the normal curve to include all values up to and including 5.
