question 83

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 ≤ 5 and n(1 − p)≤ 5
• B)np ≥ 5 and np(1 − p)≥ 5
• C)np ≥ 5 and n(1 − p)≥ 5
• D)None of these choices.
