Normal Approximation to the Binomial | |
Summary |
sometimes, it is difficult or impossible to use the binomial probability formula or tables because the value of n is too large. for large values of n and values of p close to 0.5, the normal distribution can be used instead of the binomial, if np ≥ 5 and nq ≥ 5 continuity corrections need to be used. |
Key Skills |
