Transcribed Image Text:TABLE 12-11
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 sharewares that he has developed:
