Question
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 League A park than when visiting League B parks. To test this claim,
andom sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts a) through d) below.
Determine the P-value for this test
P-value = (Round to three decimal places as needed.)
State the appropriate conclusion. Choose the correct answer below.
O A. Do not reject Ho. There is not sufficient evidence at the level of significance to conclude that games played with a designated hitter result in more runs.
OB. Reject Ho. There is not sufficient evidence at the level of significance to conclude that games played with a designated hitter result in more runs.
OC. Do not reject Ho. There is sufficient evidence at the level of significance to conclude that games played with a designated hitter result in more runs.
OD. Reject Ho. There is sufficient evidence at the level of significance to conclude that games played with a designated hitter result in more runs.
d) Construct a 99% confidence interval for the mean difference in the number of runs scored by League A teams in a League A park and the number of runs scored by League A teams in a League B park. Interpret the interval.
