In 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 runs. 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 League 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) below.

Two boxplots, one above the other, share a horizontal axis labeled from 0 to 15 in increments of 1. The bottom boxplot is labeled A and has vertical line segments drawn at 4, 6, and 7. A box encloses the vertical line segments, and horizontal line segments extend from both sides of the box to 0 and 13. An x is plotted at 14. The top boxplot is labeled B and has vertical line segments at 3, 4.5, and 7. A box encloses the vertical line segments, and horizontal line segments extend from both sides of the box to 0 and 11.

Does there appear to be a difference in the number of runs between these situations?
A. No but the number of runs scored in a League A park appear to be slightly higher than the number of runs scored in a League B park.
B. Yes because the number of runs scored in a League B park appear to have a higher median than the number of runs scored in a League A park.
C.Yes because the number of runs scored in a League A park appear to have a higher median than the number of runs scored in a League B park.
D.No because the number of runs scored in a League A park is about the same as the number of runs scored in a League B park.
b) Explain why a hypothesis test may be used to test whether the mean number of runs scored for the two types of ballparks differ.
Select all that apply.
A.Each sample has the same sample size.
B.Each sample is obtained independently of the other.
C.Each sample size is small relative to the size of its population.

c) Test whether the mean number of runs scored in a League A park is greater than the mean number of runs scored in a League B park at the
alphaα=0.05 level of significance.
Determine the null and alternative hypotheses for this test. Let mu Subscript Upper AμA

A. We are 95%confident the difference between the mean number of runs scored in a League A park and the mean number of runs scored in a League B park is between nothing and nothing.The confidence interval does not containdoes not contain zero, so there is sufficient evidence to conclude there is a difference in the mean number of runs scored with or without the DH.
B. We are 95% confident the difference between the mean number of runs scored in a League A park and the mean number of runs scored in a League B park is between nothing and nothing.The confidence interval contains zero, so there is notis not sufficient evidence to conclude there is a difference in the mean number of runs scored with or without the DH.

On January 2, Park borrowed $60,000 and used the proceeds to obtain 80 percent of the outstanding common shares of Strand. The acquisition price was considered proportionate to Strand’s total fair value. The $60,000 debt is payable in 10 equal annual principal payments, plus interest, beginning December 31. The excess fair value of the investment over the underlying book value of the acquired net assets is allocated to inventory (60 percent) and to goodwill (40 percent).
