a) Write the LS regression equation andinterpret each of the (partial) slope parameter estimates, i.e.,ˆβ1, ˆβ2 and ˆβ3.b) For steer #3, Calculate the predicted feedlottime and the residual.c) Write the residual standard deviation andinterpret.d) Give a 95% confidence interval for β1.Interpret your confidence interval.e) Determine whether ANTIBIO has statisticallysignificant predictive value when entered as the lastpredictor in the equation. Conduct a statistical testand include all steps of a hypothesis test.f) Determine whether the three predictors togetherhave statistically significant predictive value. Conduct astatistical test and include all steps of ahypothesis test.g) Calculate the coefficient of determination andinterpret.h) Suppose x1 = PROTEIN, x2 = ANTIBIO and x3 =SUPPLEM, and you enter these predictors in the model in theorder of x1,x2,x3. Find SSR(x2 |x1) and SSR(x3 |x1,x2). Whatdo they mean?i) Test whether adding ANTIBIO and SUPPLEMprovides any additional predictive value, given that PROTEINis already in the model. Include all steps ofa statistical test.
