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
sharewares that he has developed:
Simple Linear Regression 13-43
-True or False: Referring to Scenario 13-11, the null hypothesis for testing whether there is a
linear relationship between revenue and the number of downloads is "There is no linear
relationship between revenue and the number of downloads".
