Suppose researchers surveyed 52 expecting mothers at a “Future Mothers” class on their attitudes on the use of formula vs. breastfeeding. The survey results found that 20% of expecting mothers favored the use of formula over breastfeeding. Using 5,000 Bootstrap samples, we calculate a 95% confidence interval to be 18.8% to 21.2% . Indicate what would happen to the width of the confidence interval if the changes below were made. For each option, assume all other quantities are held constant.
