Cоnsider the regressiоn оutput here. The model hаs three explаnаtory variables. HIGH is an indicator variable that equals 1 when X1 > 20. R shows HIGH:X2p as an explanatory variable and that term is an interaction term between HIGH and X2p. Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) 6.62428 0.25412 26.067 < 2e-16 ***HIGH 0.60691 0.34288 1.770 0.0792 .

[a]. b) What is the predicted value for an observation where X1=18.5 and X2=2.23? [b]. c) Based on the results if were required to remove one of the terms in the model which is the term to remove? [c]. d) Suppose you were to graph the response variable against X2p where the response variable is measured on the vertical axis. You impose a regression line showing the fitted values function on the graph. For which values of X1 is the slope of the regression line (fitted values function) steeper? [d]. e) Suppose X1=22. What is the marginal impact of a 1 unit increase in X2p in the model above? [e].
