Read the description below: Kyler, the local dogcatcher, predicts that dogs at the pound will bark less when they are fed expensive name-brand food than when they are fed a cheaper generic brand of dog food. To test his hypothesis, he feeds one group of dogs the expensive brand name food for 1 week and records the number of barks during the 1-hour period following each feeding. The next week, he feeds an entirely different group of dogs the cheaper generic brand food for I week and records the number of barks during the 1-hour period following each feeding. The data for the dogs follow.
