John believes that as he increases his walking speed, his pulse rate will increase. He wants to model this relationship. John records his pulse rate, in beats per minute (bpm), while walking at each of seven different speeds, in miles per hour (mph). A scatterplot and regression output are shown below.

Solution

Pulse rate = constant_coef+speed_coef*speed

Hence the regression line will be,

y = 63.457+16.2809x

where y represents pulse rate

and x represents speed
