Question

ou want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p∗=12%p∗=12%. You would like to be 90% confident that your esimate is within 0.5% of the true population proportion. How large of a sample size is required?

n =

Do not round mid-calculation. However, use a critical value accurate to three decimal places.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
