**MathGuru**, Friday, March 2, 2012 at 4:51pmExample of a proportional confidence interval formula:

CI99 = p + or - (2.58)[√(pq/n)]

...where p = x/n, q = 1 - p, and n = sample size.

Note: + or - 2.58 represents 99% confidence interval.

For p in your problem: 7/200 = .035

For q: 1 - p = 1 - .035 = .965

n = 200

I let you take it from here to calculate the interval.
