A Big 10 University has been approached by Wilson Sporting Goods. Wilson has developed a football designed specifically for practice sessions. Wilson would like to claim the ball will last for 500 practice hours before it needs to be replaced. Wilson has supplied six balls for use during spring and fall practice. The following data have been gathered on the time used before the ball must be replaced.
Hours
551…………………511
479…………………435
440…………………466
Do you see anything wrong with Wilson claiming the ball will last 500 hours?
