Question

assume that the given procedure yields a binomial distribution with n trials and the probability of success for one trail is p. Use the given values of n and p to find the mean and standard deviation. Also, use the range rule of thumb to find the minimum usual value and the maximum. 

In an analysis of preliminary test results from a gender-selection method, 44 babies are born and it is assumed that 50% of babies are girls. So n = 44 and p = 0.5

Answer 1

no=mean-22

var=npq= 11

sd=sqrVar= sqr11

min=0, max=44
