Consider the following data for a dependent variable y and two independent variables, T1 and T2. L2 y 29 12 95 46 10 109 24 17 113 51 17 178 40 6 94 51 19 176 74 8 171 36 13 118 60 14 142 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. y = Predict y if 21 = 45. y = b. Develop an estimated regression equation relating y to $2. 9 = + 2 Predict y if $2 = 15. 9 = c. Develop an estimated regression equation relating y to 21 and T2. + 21+ Predict y if 21 = 45 and x2 = 15. y =
