Question

In a two-proportion study, we have p1= 0.682 with a sample size of 49 and p2= 0.612 with a sample size of 54. What would be the standard error in computing a confidence interval for the difference of proportions?

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.
