1. Construct a 95% confidence interval for the population proportion of nonprofits that indicate turnover as the biggest employment challenge at their organization. (Type integers or decimals. Round to three decimal places asneeded.)
2. If you wanted to conduct afollow-up study to estimate the population proportion of nonprofits that indicate turnover as the biggest employment challenge at their organization to within 0.02 with 95% confidence, how many nonprofits would yousurvey? (Round up to the nearestinteger.)
