An instructional video on pitching claims that after undergoing the training on the video, players will be able to throw strikes on at least 60% of their pitches. TO test this claim, 20 little leaguers throw 50 pitches each before and after undergoing the training. THe table records the number of strikes out of 50 that each player threw. use a significance level of 0.05

Before: 29 29 29 31 33 31 31 33 32 30 30 30 33 34 34 36 37 35 35 36

After: 35 36 32 29 31 31 32 34 32 36 34 34 32 31 32 34 37 33 34 33

is there evidence that the training is effective in improving a players ability to throw strikes?

Use After- Before as the difference and test the new hypothesis.
