Question

A sample is used to construct a confidence interval for an unknown population Which of the following is the least likely to result in a decrease in the margin of error?

Increasing the sample size
Increasing the confidence level
Decreasing the confidence level
A change in the standard deviation of the

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.
