When we use a normal distribution to approximate a binomial distribution, why do we make a continuity correction?
Added by Encarnacion W.
Step 1
The probability of having exactly k successes in n trials is given by: $$P(X=k) = \binom{n}{k} p^k (1-p)^{n-k}$$ On the other hand, a normal distribution is a continuous probability distribution, characterized by its mean ($\mu$) and standard deviation Show more…
