The MuscleUp Powder

Larry can only do three push ups but he wants to be able to do more. He hears another guy at the gym say that he has been using “MuscleUp” powder and he has increased the number of push ups that he can do. Larry reads about MuscleUp on the internet and decides that he will try it. For four weeks he does not take the supplement. Then he takes the ½ cup supplement each day for four weeks. The data that he collected is in the chart below. Then Larry does the entire experiment again to test his prior results.
