True/False

SCENARIO 13-11
A computer software developer would like to use the number of downloads (in thousands)for the trial
version of his new shareware to predict the amount of revenue (in thousands of dollars)he can make
on the full version of the new shareware.Following is the output from a simple linear regression
along with the residual plot and normal probability plot obtained from a data set of 30 different
