**MathGuru to LT**, Thursday, November 1, 2007 at 7:43pmHere's a hint:

Use a confidence interval formula for proportions. Here's one example:

CI99 = p + or - (2.58)(sqrt of pq/n)

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

Remember you need a 90% confidence interval; my example uses a 99% confidence interval. You will need to adjust accordingly.

Another hint: x = 229, n = 525

I hope this will help.
