In general, the binomial probability P(X x) is approximated by the area under the normal curve to the right of x - 0.5.

Question

In general, the binomial probability P(X  x) is approximated by the area under the normal curve to the right of x - 0.5.

Quizplus · Accepted Answer

This is known as the continuity correction and is a commonly used technique to approximate the binomial distribution with the normal distribution. By subtracting 0.5 from the value of x, we account for the fact that the binomial distribution is discrete, while the normal distribution is continuous.
