**MathGuru**, Monday, March 15, 2010 at 6:58pmTry this formula:

n = [(z-value)^2 * p * q]/E^2

Note: n = sample size needed; .5 for p and .5 for q are used if no value is stated in the problem. E = maximum error, which is .03 in the problem. Z-value is found using a z-table to represent 90% interval. Round final result to next highest whole number.

Also: ^2 means squared and * means to multiply.

I hope this will help get you started.
