What effect does increasing the sample size have on the confidence interval? Increasing the sample size decreases the margin of error and makes the confidence interval narrower. Increasing the sample size has no effect on the margin of error. Increasing the sample size decreases the margin of error and makes the confidence interval wider. Increasing the sample size increases the margin of error and makes the confidence interval wider.
