During the recent US Presidential election exit polls were conducted throughout the nation. A California exit poll showed 64% of 700 women questioned voted for President Biden. Nationally 55% of a sample of 1550 women voted for President Biden. We are interested in estimating (with 95% confidence) the difference between the proportion of California women that voted for President Biden and the proportion of women that voted for Biden nationally. Use the shortcut formula to compute a 95% confidence interval for the difference in the two proportions The confidence interval is A. (. 359, 426) B. (.046, .133) C. (-.046, .133) D. (.225, 426) E. (.001, .326)
