  • statistics -

    You will need a confidence interval formula for the difference of two population proportions.

    Here is one such formula:

    CI95 = (p1-p2) ± 1.96 [√(p1q1/n1 + p2q2/n2)]

    Your data:

    p1 = .62
    q1 = 1 - p1 = .38
    p2 = .24
    q2 = 1 - p2 = .76
    n1 = 150
    n2 = 200

    Substitute your data into the formula and calculate the confidence interval.
