Exercise 20

Suppose the estimated slope coefficient in a regression model measuring the association between the independent variable exercise (in hours per week) and dependent variable pulse has a slope of –0.05 (per minute). Interpret this result.

Step 1 of 2

The estimated least squares regression equation is given by:

where is the estimate of slope. The dependent variabledepends on the explanatory variable (independent variable). The most important part of the above regression line is the slopewhich depicts the change in predicted value ofdue to one unit change in variable.
