Use the rule-of-thumb test to check whether a normal distribution (with the same mean and standard deviation as the binomial distribution) is a suitable approximation for the binomial distribution with given the properties:
-n = 400, p = 0.06

Question

Quizplus · Accepted Answer

The rule-of-thumb test states that a normal distribution is a suitable approximation for the binomial distribution if both np and n(1-p) are greater than 5. Here, np = 400 * 0.06 = 24 and n(1-p) = 400 * 0.94 = 376, both of which are greater than 5, satisfying the condition.
