Question

100%

Construct a 90% confidence interval to estimate the population proportion with a sample proportion equal to 0.35 and a sample size equal to 120.

A 90% confidence interval estimates that the population proportion is between a lower limit of ____?____and an upper limit of ____?____

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.
