Question

Assume that a sample is used to estimate a population proportion p. Find the 98% confidence interval for a
sample of size 207 with 24.2% successes. Enter your answer as a tri-linear inequality using decimals (not
percents) accurate to three decimal places.
< p <
Answer should be obtained without any preliminary rounding. However, the critical value may be rounded
to 3 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.
