Construct a 95% confidence interval for the population proportion of non-profits that indicate turnover as the biggest employment challenge at their organization. 2. If you wanted to conduct a follow-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 you survey? 3. If you wanted to conduct a follow-up study to estimate the population proportion of nonprofits that indicate turnover as the biggest employment challenge at their organization to within ± 0.03 with 95% confidence, how many nonprofits would you survey?
