Find the mean and standard deviation for each binomial random variable:

a. n = 36, ππ = .75 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)

b. n = 75, ππ = .55 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)

c. n = 26, ππ = .90 (Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)
