Question 1

When you construct a 90% confidence interval for a population proportion based on a sample, what is it that you are pretty sure is in your interval?

◦ None
◦ I and II
◦ II only

Question 2

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.
