Exercise 15.02 Algo (Least Square Method) Consider the following data for a dependent variable y and two independent variables, o and gy. 30 12 94 46 10 108 25 17 113 50 16 178 41 6 95 51 20 176 75 7 171 36 12 117 59 14 143 76 16 212 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 *1. 1 = + 1 Predict y if =1 = 46. b. Develop an estimated regression equation relating y to *2- 1= + Predict y if = = 26. c. Develop an estimated regression equation relating y to a1 and ay- 1 = + 01 + Predict y if =1 = 46 and x, = 26. 1=
