Diabetes is a serious health condition. In the year 2000, 4.7% of American males had diabetes. In the year 2008, 6.3% of American males had diabetes. Let y be the percentage of American males with diabetes in the year x, where x = 0 represents the year 200.
(a) Find a linear equation which could be used to predict the percentage of American males with diabetes in a given year x, where x = 0 represents the year 2000. The slope of your linear equation should be accurate to two decimal places, i.e., to the nearest hundredth.
Explain/show work. (b) Use the equation from part (a) to predict the percentage of American males with diabetes in the year 2015.
Show some work. (c) Slope and interpretation:
• What is the slope of the equation in part
(a) and what are the units of measurement?
• In a sentence, interpret what the slope is telling us, in the context of this real-world application involving the percentage of American males with diabetes.
