- Sec 3.5 Q16arrow_forwardIn 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.

The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterarguement? A. Even 0.08 degrees is a lot and thus should be considered. B. The margin of error is just extra information and thus can be ignored. C. The difference with any previous decade is much greater than the margin of error. D. 0.15 - 0.08 is 0.07, which is still an increase and thus should be considered.arrow_forward
- A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

A. What is (are) the independent variable(s)?arrow_forwardChapter 6, Section 4-HT, Exercise 218 - MathPad Mind-Set MattersIn 2007 a Harvard psychologist set out to test her theory that ‘‘Mind-Set Matters.”1 She recruited 75 female maids2 working in different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon General’s recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the informed group had lost an average of 1.79 lbs (s=2.88) and the uninformed group had lost an average of 0.2 lbs (s=2.32). The data are stored in MindsetMatters. Based on this study, does ‘‘Mind-Set Matter”? In other words, for maids, does simply thinking they are exercising more actually cause them to lose more weight?Click here for the dataset associated with this question.1Crum, A. and Langer, E.,…arrow_forward
