Multiple Choice

Given a binomial distribution with n trials and probability p of a success on any trial,a conventional rule of thumb is that the normal distribution will provide an adequate approximation of the binomial distribution if

• A) np \(\le\) 5 and n(1- p)\(\le\) 5
• B) np \(\ge\) 5 and np(1 -p)\(\ge\) 5
• C) np \(\ge\) 5 and n(1 -p)\(\ge\) 5
• D) None of these choices.
