**MathGuru**, Monday, November 5, 2012 at 7:27pmStandard error = √(p1(1-p1)/n1 + p2(1-p2)/n2)

Your data:

n1 = 384

n2 = 432

p1 = 112/384

p2 = 91/432

If you substitute the data into the formula above, you should find standard error to be .0303, which will narrow down your choices. I'll let you determine the pooled value for p.

**Robert**, Monday, March 3, 2014 at 2:53pm@John I have come from a year later to reply to your concern, to uproot this tyranny that is Math Guru. No longer shall we sit wondering what the other half of the question is. No longer must we be given a formula and have to solve it out. NO LONGER MUST WE SIT THROUGH THIS.

The answer is E.
