The margin of error for a 99% confidence interval for each study can be found as follows: $\large MoE(N.Ga)=2.576\sqrt{\frac{0.84(1-0.84)}{3000}}$ $\large MoE(S.Ga)=2.576\sqrt{\frac{0.75(1-0.75)}{2000}}$ Note: The margin of error can be converted into a percentage, if necessary, by multiplying by 100.
