Question

pmework Consider the following data for a depe dependent variable y and two independent variables, I and 22- Round your all answers to two decimal places. Enter negative values as negative numbers, if necessary. a. Develop an estimated regression equation relating y to 31. Predict y if Ij = 45. b. Develop an estimated regression equation relating y to 12. Predict y if x2 = 15. c. Develop an estimated regression equation relating to and Predict y if x = 45 and 3) = 15.

Answer 1

a) y = 47.8 + 1.892 x1

Predicted y for x1=45 is   132.94

b) y = 93.5 + 3.58 x2

Predicted y for x2=15 is 147.2

c)  y = -14.5 + 2.002 x1 + 4.31 x2

Predicted y for x1=45, x2=15 is 140.24
