- Answer pleasearrow_forwardTwo variables, x and y are linearly related. The regression equation of y on x is y = 3.5 + 2.3x. One data point used to construct this regression equation is (5,17.5). What is the residual for this point and is the predicted value for x= 5 too small or too large? O A. 15, too small O B. -2.5, too large O C. 2.5, too large O D. -2.5, too small E. 2.5, too smallarrow_forwardPlease Explain results. Thank youarrow_forward

Data are provided in the table for a sample of 20 cities. A regression analysis was performed on the data and the results indicated that the interaction model E(y) = B,+ Bx + Bx, + Bx; + B,xqx,+ B;xx; + Bzxzx; was a good model to fit to the data. %3D However, the residual plot for this model indicates that heteroscedasticity may exists for the percentage of families with annual incomes less than R24 000. How do I Conduct a test for heteroscedasticity by dividing the data into two subsamples, x,21 and x, > 21 using MSE for the first subsample = 582.3, MSE for the second subsample = 364.7 and a= 0.05.
