Suppose we have a data set with five features, X1 = GPA, X2 = IQ, X3 = Level (1 for College and 0 for High School), X4 = product between GPA and IQ, and X5 = product between GPA and Level. We want to predict student's starting salary after graduation (in thousands of dollars). Suppose we use least squares to fit a linear regression model, and estimate the parameters of the model as follows: \beta 0= 50; \beta 1 = b. Explain the effect of the low values of \ beta 2 and \beta 4 comparing to the high absolute values of \beta 1, \beta 3, and \beta 5. 20; \beta 2 = 0.07; \beta 3 = 35; \beta 4 = 0.01;
