Q1) The stopping distance (y, in feet) of a car was studied in relation to its velocity (x, in miles per hour). The stopping distances at 6 different velocities are listed below. velocities 7 stopping 24 distance 45 61 14 34 30 50 57 24 45 69 (A) Write the Regression equation for z = Vx and y (B) Plot the scatterplot for X,y and for Z,y (by Excel) (C) Compute the sample correlation coefficients of x with y and z with y. (D) Using the regression of Z on y, what is the stopping distance when the velocity(x) is 35. (E) Obtain â & in both models and interpret it (F) Obtain the coefficient of determination in both models and interpret it Compute prediction intervals (95%) for z and y when Xnew = 36. And interpret it Based on ô & ,the coefficient of determination, which model fits the data best? Explain
