A personal trainer wants to look at the relationship between number of hours of exercise per week and resting heart rate of her clients. The data show a linear pattern with the summary statistics shown below:
mean
standard deviation
2= hours of exercise per week
= 8.9
s = 4.8
y = resting heart rate (beats per minute)
y = 74.3
8 = 7.2
r=-0.88
Find the equation of the least-squares regression line for predicting resting heart rate from the hours of
exercise per week.
