[a_yhat]. b) Construct a 90% confidence interval for the coefficient on X2.  The interval is  [b_intervalX2]. c) Use the ANOVA table to calculate the MSE.  The value is [c_MSE]. d) Compare the MSE you obtain from the ANOVA table with the MSE you obtain using the regression summary.  Are these actually from the same regression? [d_no]. e) Compare the R2 values from the summary regression results and the ANOVA table.  Choose the correct statement (i) the MSE values are different but the R2 values are the same (ii) the MSE values are the same and the R2 values are the same which provides further evidence they are from the same regression (iii) the R2 value from the regression summary is larger than the R2 value from the ANOVA table (iv) the R2 value from the regression summary is smaller than the R2 value from the ANOVA table.
