Problem Statement

Standard Error of an Estimated Gender Gap In an independent survey of 500 men and 700 women, 52% of men and 46% of women plan to vote for a candidate. Which computation gives the standard error of the estimated difference in proportions? sqrt((0.52 × 0.48)/500 + (0.46 × 0.54)/700) ≈ 0.029 sqrt((0.52 × 0.48)/600) (0.46 × 0.54)/700 0.52 − 0.46 = 0.06
