Correct part d if needed

baseball, League A allows a designated hitter (DH) to bat for the pitcher, who is typically a weak hitter. In League B, the pitcher must bat. The common belief is that this results in League A teams scoring more ns. In interleague play, when League A teams visit League B teams, the League A pitcher must bat. So, if the DH does result in more runs, it would be expected that league A teams will score more runs in eague A park than when visiting League B parks. To test this claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts a) through d) elow. Click the icon to view the data table. A. Do not reject Ho. There is not sufficient e OB. Reject Ho. There is not sufficient evidenc OC. Do not reject Ho. There is sufficient evide D. Reject Ho.
