Product testing

A company is producing and market- ing new reading activities for elementary school children that it believes will improve reading comprehension scores. A researcher randomly assigns third graders to an eight- week program in which some will use these activities and others will experience traditional teaching methods. At the end of the experiment, both groups take a reading compre- hension exam. Their scores are shown in the back-to-back stem-and-leaf display. Do these results suggest that the new activities are better? Test an appropriate hypothesis and state your conclusion.
