(Round your numerical values to one decimal place.) y = Predict y ifx, = 76. (Round your answer to one decimal place.) (b) Develop an estimated regression equation relating y to Xy. (Round your numerical values to one decimal place.) P= Predict y if x2 = 16. (Round your answer to one decimal place.) Develop an estimated regression equation relating y to x, and xz. (Round your numerical values to one decimal place.) Predict y if X1 - 76 and X2 - 16. (Round your answer to one decimal place.)
