a.Estimate a regression model with the predictor variablesxandd, and then extend it to also include the interaction variablexd. What is the estimated regression coefficient for the predictor variablex in both models?(Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) )

Model 1(No Interaction) =

Model 2 (Interaction)=

a-2.Use the preferred model to predicty. (Round coefficient estimates to at least 4 decimal places and final answers to 2 decimal places.)
