A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the meantuition and fees for private institutions in California is greater than $35.000?

Suppose you are a basketball coach and you've taken some measures on your starting five players. The two measures that you're most interested in right now are scores on a two-minute jump shot test (x) and time in seconds on a shuttle run (y). You want to determine a couple of things:1) On which variable (jump shots or shuttle run time) are your starters more consistent? 2) For player #1, is she a faster runner or better at jump shots? 3) For player #4, is she a faster runner or better at jump shots?

1) For each of the following pairs of variables, is there likely to be a positive association, a negative association or no association? Briefly explain your reasoning. (a) Amount of alcohol consumed and performance on a test of coordination. (CHOOSE ONE) i) There is likely to be a positive association. As alcohol consumption increases, performance on a test of coordination will tend to increase. ii) There is likely to be a negative association. As alcohol consumption increases, performance on a test of coordination will tend to decrease. iii) No association would be expected between amount of alcohol consumed and performance on a test of coordination. (b) Height and grade point average for university students. i) There is likely to be a positive association. As height increases, grade point average for university students will tend to increase.There is likely to be a negative association. As height increases, grade point average for university students will tend to decrease.…
