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.
