Work Step by Step
To use the normal distribution to approximate the binomial distribution,
the following conditions should be met:
1. $np\geq5$ and $nq\geq5$,
2. a correction for continuity in the normal approximation.
A correction for continuity is a correction employed when a continuous distribution
is used to approximate a discrete distribution.
For example, for any specific value of X, say 8, the
boundaries of X in the binomial distribution (in this case, 7.5 to 8.5) must be used.
