Question 15 What effect does sample size have on the width of the confidence interval? Changing the sample size has no effect on the width of the confidence interval. Increasing the sample size will increase the width of the confidence interval. Decreasing the sample size will decrease the width of the confidence interval. Increasing the sample size will decrease the width of the confidence interval.
