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?
I. 90% of the sample data.
II. 90% of all sample proportions.
III. The population proportion.
◦ III only
◦ I only
◦ 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.
◦ The corrected interval will be one-fourth as wide.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
