You work at a company that makes a drug (DeFuzz) to treat Fuzzy eye disease. (I made this up- I don’t think there is such a condition) The prevalence of Fuzzy eye disease in the U.S. is 0.5%. Most infected don’t know they have Fuzzy eye disease until vision is impaired years later. Your company funds a non-profit organization to offer free screening for Fuzzy eye in Michigan. The group screens 800 Michiganders per week for 3 weeks. The screening test’s sensitivity is 90% and specificity is 95%. Your boss asks you to predict how much increase in demand for DeFuzz will occur because of the screening activity. To help predict increased demand for DeFuzz, determine:

How many people you expect to test positive over the 3 week period?

What assumption did you make in order to estimate the number of positive tests to expect?

Do you think this is a reasonable assumption to make? Why or why not?

Of those who test positive, how many would you expect to have Fuzzy Eye disease?
