Assume a binomial probability distribution with n = 40 and = 0.55.
Compute the following: (Round the value for standard deviation and intermediate calculations to 2 decimal places and your final answer to 4 decimal places.)
(a) The mean and standard deviation of the random variable.
(b) The probability that X is 25 or greater
(c) The probability that X is 15 or less.
(d) The probability that X is between 15 and 25, inclusive
