Given information
Swim yards and the student’s heart rate (beats per minute) after swimming on a random sample of days:
Step-by-step explanation
Step 1.
The point generates the largest residual of which means that the observed heart rate is almost beats less than our predicted rate of beats per minute. When the point is removed, the slope becomes with the y-intercept changing to . This linear association is still very weak, we see that the removed data pair can be considered an influential point in the sense that -intercept becomes more meaningful.
Difference between the observed value of the dependent variable ( ) and the predicted value of ( ) is called the residual ( ). Each data point has one residual value.
