Question: Setup a predictive equation involving variable 1 and variable 2. First, plot the DATA to determine if linear regression applies. Then decide: A. linear regression

Setup a predictive equation involving variable 1 and variable 2. First, plot the DATA to determine if linear regression applies. Then decide:

A. linear regression equation will be very useful because the points have a strong linear pattern.

B. linear regression is not applicable because the point pattern is curvilinear (has a curve).

C. linear regression is not applicable because it appears that there are two linear patterns indicating that the data comes from two populations.

D. linear regression is not useful because the point have no discernible pattern.

E. You need more information before deciding to use linear regression.
