Question

Create a 95% confidence interval for the population proportion of Orange candies.
sample size is 30, point estimate is 0.44, critical z value is 0.152. Standard error is 0.602. Margin of error is 0.017

what is the lower bound and upper bound and interpretation?

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.
