Question:
Use the data collected in data project 6 of Chapter 2 regarding heart rates. Is there a linear relationship between the heart rates before and after exercise? How much of the variability in heart rate after exercise is explained by heart rate before exercise? Write a regression equation to determine what heart rate after exercise you would expect for a person, given the person’s heart rate before exercise.
Data from in project 6
Have each person in class take his or her pulse and determine the heart rate (beats in 1 minute). Use the data to create a frequency table with 6 classes. Then have everyone in the class do 25 jumping jacks and immediately take the pulse again after the activity. Create a frequency table for those data as well. Compare the two results. Are they similarly distributed? How does the range of scores compare?
