**MathGuru**, Tuesday, October 5, 2010 at 8:24pmUsing a formula for a binomial proportion one-sample z-test with your data included, we have:

z = .25 - .18 -->test value (310/1240 = .25) minus population value (.18)

divided by

√[(.18)(.82)/1240] -->.18 is test value, .82 is 1 - .18, and 1240 is the sample size

Finish the calculation for the value of the test statistic.
