The students randomly selected one computer of each type. The students went to the Microsoft game Web site and clicked on the download link for the NBA game. The time (in seconds) between clicking on the link and the completion of the download was recorded. Using ANOVA, they compared the download times with a resulting p-value of 3.43 E-12.
