The volume (in cubic feet) of a black cherry tree can be modeled by the equation y = - 51.3 + 0.4x, +5.2x,, where x, is the tree's height (in feet) and x, is the tree's diameter (in inches). Use the multiple regression equation to predict the y-values for the values of the independent variables. (a) x, = 71, x2 = 8.9 (b) x, = 65, x2 = 11.4 (c) x, = 81, x2 = 17.2 (d) x, = 88, X2 = 2 %3D (a) The predicted volume is cubic feet. (Round to one decimal place as needed.)

Chris collects personal data on coffee consumption x (in cups) and the following night's sleep y (in hours). Fitting a linear regression to the data, Chris learns that the slope is -0.43. One evening Chris uses his regression and predicts 6.47 hours of sleep. Then Chris remembers that his "coffee count" was off in making this estimate; Chris drank in an atypical additional 2 cups of coffee over lunch break. What should Chris' predicted sleep be (in hours)? Answer to the nearest 0.01 hours. (There is insufficient information here to produce the equation of the least squares line. You may need to look back in the course notes to find out how the slope is interpreted, and how that can be used to solve this problem.)
The volume (in cubic feet) of a black cherry tree can be modeled by the equation y = - 51.7 +0.4x, +4.7x2, where x, is the tree's height (in feet) and x, is the tree's diameter (in inches). Use the multiple regression equation to predict the y-values for the values of the independent variables. (a) x, = 72, x2 = 8.7 (b) x, = 65, x2 = 10.2 (c) x4 = 81, x2 = 17.5 (d) x, = 90, x2 = 20.7 %3D (a) The predicted volume is cubic feet. (Round to one decimal place as needed.)

A researcher is studying the relationship between self-esteem (X) and romantic jealousy (Y). She finds that these variables are related by the equation Ŷ = –2.24(X) + 6.72. Which of the following statements is a CORRECT interpretation of what the slope and/or intercept is telling you in this regression equation? Group of answer choices For every one unit that jealousy increases, self-esteem is predicted to go up by 6.72 units. For every one unit that self-esteem increases, jealousy is predicted to go down by 2.24 units. For every one unit that jealousy increases, self-esteem is predicted to go down by 2.24 units. For every one unit that self-esteem increases, jealousy is predicted to go up by 6.72 units.
