Question

100%

You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 90% confident that your estimate is within 2.5% of the true population proportion. How large of a sample size is required?

n =
Do not round mid-calculation. However, use of a critical value rounded to three decimal places will suffice.

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.
