**MathGuru**, Saturday, November 3, 2012 at 6:16pmFormula to find sample size:

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

... where n = sample size, z-value is found using a z-table for 95% confidence (which will be 1.96), p = .30, q = 1 - p, ^2 means squared, * means to multiply, and E = .025 (2.5%)

Convert all fractions to decimals, then plug values into the formula and calculate n. Round your answer to the next highest whole number.
