This problem asks you to explore how changing the confidence level, the desired margin of error, or the guess for the population proprotion impacts the sample size estimate. For the first row in the table, you will be asked to find the sample size for a 90% confidence interval with a desired margin of error of 1.5% assuming the population proportion is p = 87%. The following three rows will change one of these three values (holding the others to the same values given in the first row). Find the sample size for all four scenarios, and then reflect on how the sample size requirement changes as the confidence level increases, as the desired margin of error becomes more precise, and as the guess for the population proportion approaches 50%. Desired |] Estimate for Confidence |] Margin |] Population Necessary Proportion Sample Size
