Question
1.) Fill in the blanks. Based on the intent of the physician's study, the predictor variable, X, is_____ and the response variable, Y, is______.
2.) As described in the article, the relation between age and peak heart is a_______.
- positive relation
- negative relation
- no relation
3.) Provide the regression line, ŷ= a+bx. Show steps/equations used to get answer.
4.) Suppose a 40 year old person is randomely selected. Use your model to predict their peak heart rate.
5.) Based on your model, as a person ages one year, how much would you expect peak heart rate to change?
Transcribed Image Text:An article read by a physician indicated that the maximum heart rate an individual can reach during intensive
exercise decreases with age.
The physician decided to do their own study to see if Age can be used to estimate Peak Heart rate.
Six randomly selected people performed exercise tests and recorded their peak heart rates.
The results are shown in the following table.
