Assuming That All Conditions Are Met to Approximate a Binomial $P ( x \leq 23 )$

Multiple Choice

Assuming that all conditions are met to approximate a binomial probability distribution with the standard normal distribution, then to compute $P ( x \leq 23 )$ from the binomial distribution we must compute as the normal approximation.

A) $P ( x \leq 23.5 )$
B) $\mathrm { P } ( \mathrm { x } \geq 23.5 )$
C) $\mathrm { P } ( \mathrm { x } \leq 22.9 )$
D) $\mathrm { P } ( \mathrm { x } \leq 23.1 )$
