Question

Suppose you've computed the following least-squares regression line, = 8.5 - 0.25x,where:
x = degrees in Fahrenheit
y = number of miles of jogging in a day

Interpret the regression coefficient of this line.

The average miles of jogging on a 70 degree day is 8.5.

For each increase of one degree in temperature, we'd predict that an individual would jog 0.25 more miles.

For each increase of one degree in temperature, we'd predict that an individual would jog 0.25 fewer miles.

For each increase of one degree in temperature, we'd predict that an individ
