Question

18. In the most recent census it was found 65% of those living in one state owned their own home. What sample size is needed to construct the 95% confidence interval to within 0.04 ?

D. 944

C. 770

B. 547

A. 385

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.
