Find the mean and standard deviation for each binomial random variable: a. n = 56, = .95 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.) b. n = 95, = .75 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.) c. n = 48, = .90 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)
