Question

se the formula in this example to determine the sample size, n.

The estimated prevalence is 18%, and the desired confidence level is 91% with a margin of error of 4%. (Round your answer to the nearest integer.)
n =

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.
