What is the probability that exactly half the male adults will be less than 62 inches tall?
Let X be the height of a male adult. Then P(X<62) = P(Z<-1.2) = 0.1151
Number of male adults who are less than 62 inches tall follows a binomial distribution with n =12 and p = 0.1151 . Then P(exactly 6 under 62 inches) = 0.00103
