Questions:
- Using the graph in the interactive
application, what is the age estimate of a woman who has a target heart rate
of 112? Next, use the formula 0.65(220 – A) to estimate. Check your
work by entering the heart rate into the interactive application. Did all
of the methods give you the same answer? Explain your answer.
