We have calculated a confidence interval based on a sample of size n = 100. After looking over our work, we realized that the sample size was actually 400. How will the corrected interval compare to the original interval?

▸ The corrected interval will be the same width.

▸ The corrected interval will be twice as wide.

▸ The corrected interval will be four times as wide.

▸ The corrected interval will be one-half as wide.

▸ The corrected interval will be one-fourth as wide.
