It has been reported that 83% of federal government employees use email. If a sample of 200 federal government employees is selected, find the mean, variance, and standard deviation of the number who use email.

    mean = np
    variance = npq
    standard deviation = square root of the variance

    n = 200
    p = .83
    q = 1 - p

    I'll let you take it from here.
