Question 17 (0.5 points) I: You know that many studies have demonstrated that exercise decreases scores on the Beck Depression Inventory (BDI; Beck, Ward, Mendelson, Mock, & Erbaugh, 1961), but you want to know if gardening provides sufcient exercise to have the same effect. The average BDI score among people similar to those you will be studying is 15. What would be your alternative research hypothesis? O Gardening will decrease BDI scores. O Gardening will increase BDI scores. O Gardening will have no effect on BDI scores. 0 Gardening will have no effect on or increase BDI scores. 0 Gardening will have no effect on or decrease BDI scores.

What would be your null research hypothesis? 0 Gardening will decrease BDI scores. 0 Gardening will increase BDI scores. O Gardening will have no effect on BDI scores. O Gardening will have no effect on or increase BDI scores, 0 Gardening will have no effect on or decrease BDI scores.

If you were going to replicate a study examining whether there is truly a greater chance of a batter being hit by a pitch when the temperature increases, what would be your alternative research hypothesis? You know that the average chance of a batter being hit during normal temperatures (70 degrees) is 2 times per game. 0 Pitchers will hit batters two or fewer times per game when the temperature is greater than 70 degrees. 0 Pitchers will hit batters more than two times per game when the temperature is greater than 70 degrees. Pitchers will hit batters two times per game when the temperature is greater than 70 degrees. O Pitchers will NOT hit batters two times per game when the temperature is greater than 70 degrees; they will hit batters more or fewer than two times per game.
