Consider the following data for a dependent variable y and two independent variables, @1 and #2. C1 y 29 13 95 47 11 109 24 18 112 50 16 179 41 6 95 51 20 176 75 8 170 37 13 118 60 14 142 77 16 211 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 21 . y = I+ Predict y if $1 = 45. y = b. Develop an estimated regression equation relating y to x2. y = 1+ Predict y if *2 = 25. y = c. Develop an estimated regression equation relating y to *1 and 232. y = + 1+ Predict y if #1 = 45 and x2 = 25. y =
