Question 1. A statistics teacher collected data on 18 different students in their class, measuring their resting heart rate and surveying the number of hours that each student exercised per week. The line represents the linear function that is used to determine a student's resting heart beat from the number of hours of exercise per week. Was the average heart rate among students closer to the range 80-70 beats per minute (bpm) or 55 - 45 bpm? Explain how you decided.
