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 the standard deviation. Also, use the range rule of thumb to find the minimum usual value -2 SD and the maximum usual value mean + 2 SD.
In an analysis of preliminary test results from the a gender selection method, 37 babies are born and it is assumed that 50% of babies are girls so n=37 and p =0.05
The value of the mean is =
The value of SD=
The maximum usual=
The min usual=
