Quiz #1: Measures of Disease Occurrence

Instructions: As you take this test, please keep in mind the following guidelines:

Examples of percentages: 2%  46%  33.2%   99.83%

Examples of proportions: 0.02  0.46  0.332  0.9983

Examples of integers: 2  46  33  100

When we ask for a value rounded to the 10th decimal place, we mean that there is one digit after the decimal point: 33.2%  0.4

Also, it's always a good idea to use non-rounded values in your calculations and then round at the end. If you round before the end of your calculations, and then use the rounded value to calculate subsequent answers, you may end up far from the correct answer.

Good luck!
