Find the standard deviation, Sigma, for the binomial distribution which has the stated values of n and p. Round your answer to the nearest hundredth.
n = 639; p = 0.7

  • statistics -

    standard deviation = √npq

    n = 639
    p = 0.7
    q = 1 - p

    I'll let you take it from here to calculate.
