These parts did not fit in the picture D) Graph the least - square line. Be sure to plot the X and Y, as a point on the lineE) find the value of the coefficient of the determination R^2. What percentage of the variation in Y can be explained by the corresponding variation in X and the least - Square line? What percentage is unexplained? Round your answer for R^2 to four decimal places. Round your answers for the percentages to two decimal placesR^2=Explained= %Unexplained= %F) considering the values of R and R^2 does it make sense to use the lease squared line for prediction ? explain your answer.

8. [-/5.31 Points] DETAILS BBUNDERSTAT12 9.2.014.S. MY NOTES ASK YOUR obtained. Does prison really deter violent crime? Let x represent percent change in the rate of violent crime and y represent percent change in the rate of imprisonment in the general U.S. population. For 7 recent years, the following data have been x | 6.2 5.4 4.1 5.2 6.2 6.5 11.1 y -1.6 -4.4 -6.8 -4.0 3.6 -0.1 -4.4 LA USE SALT Complete parts (a) through (e), given Ex = 44.7, Ey = -17.7, Ex = 315.35, Ey? = 116.49, Exy = -109.53, and r = 0.0755. (a) Draw a scatter diagram displaying the data. 11 - 10 y (percent change in the rate of imprisonment y (percent change in the rate of imprisonment) y (percent change in the rate of imprisonment -2 -4 -61 -6 10 5 8 9 10 11 x (percent change in the rate of violent crime) (percent change in the rate of violent crime) x (percent change in the rate of violent crime) y (percent change in the rate of imprisonment) o x (percent change in the rate of violent crime) (b) Verify the given sums Ex, Ey, Ex", Ey, Exy, and the value of the sample correlation coefficient r. (Round your value for r to four decimal places.) EX = Ly = xx2 = zy2 = Exy = (c) Find x, and y. Then find the equation of the least-squares line y = a + bx. (Round your answer to four decimal places.) X = y = 1 =
