Subject: Mathematics    / Statistics
Question

If np?5 and nq?5, estimate P(more than 4) with n=14 and p=0.3 by using the normal distribution as an approximation to the binomial distribution; if np<5 or nq<5, then state that the normal approximation is not suitable.

A. P(more than 4) =
(Round to four decimal places as needed.)

B. The normal distribution cannot be used.
