(Round your numerical values to one decimal place.) y = Predict y if x1 = 76. (Round your answer to one decimal place.) (b) Develop an estimated regression equation relating y to x2. (Round your numerical values to one decimal place.) y = Predict y if X2 = 16. (Round your answer to one decimal place.) (c) Develop an estimated regression equation relating y to x1 and x2. (Round your numerical values to one decimal place.) y = Predict y if x1 = 76 and X2 = 16. (Round your answer to one decimal place.)
