**MathGuru**, Wednesday, August 1, 2012 at 8:35pmTry this formula:

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

= [(1.645)^2 * .5 * .5]/0.07^2

= ? (round to the next highest whole number)

I'll let you finish the calculation.

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 0.07 in the problem. Z-value is found using a z-table (for 90%, the value is 1.645).

I hope this will help get you started.
