Question 1 Given the following multiple regression equation: -10- x1 + 24x2 + 1103 Determine the estimated value of y when $2 =9 $3 =-1. Question 2 A multiple regression equation with 2 independent variables has the following properties: For every unit increase in 1, y decreases by 0.2 on average, holding x2 constant. For every unit increase in c2, y increases by 5 on average, holding 1 constant. o When 1 = 0 and 12 = 0, j = 29. Which of the following best represents the equation? Of = 29 - 0.2x1 - 512 Oy = 0.2x1 + 512 - 29 Oy = 29 + 0.2r] - 502 Oy = 29 + 0.2x1 + 5x2 Of = 29 - 0.2x1 + 5:2. Question 3 Given the following multiple regression equation: g = 23 + 18x1 - 2012 Select the direction of change in y and enter a positive integer in the answer box. a) If 1 increases by 1 unit while holding $2 constant, then y Select an answer by units on average. b) If 2 increases by 1 unit while holding 1 constant, then y Select an answer w by units on average.. Question 4 A multiple regression equation with 2 independent variables has the following properties: For every 3-unit increase in 1, y increases by 39 units on average, holding r2 constant. For every 5-unit increase in x2, y decreases by 35 units on average, holding r 1 constant. o When 1 = 0 and r2 = 0, 1 = 30. Which of the following best represents the equation? Oy = 30 + 3921 + 35:2 Oy = 39x1 + 3512 - 104 oy = 104 - 39r] + 39:2 Ou = 30 + 13x1 + 702 Of = 30 + 1321 - 702. Question 6 In the following multiple regression equation, what is value of x2 when c1 = 14 and y is estimated to be 258.5? 1 = 157 - m1 + 11c2
