Given the following data, develop a linear regression forecasting model for y as a function of x and solve the next question: (Note: For the quiz I have provided you with a lot of pre-calculated figures like the X^2, XY, X-bar, Y-Bar, the Sum of X^2 and the Sum of XY. On the midterm exam you will need to calculate them on your own). X Y X^2 XY 4 2 16 8 3 4 9 12 10 5 100 50 5 4 25 20 8 4 64 32 Sum 30 19 214 122 X-Bar = 6 Y-Bar = 3.8 Sum of X^2 = 214 Sum of XY = 122 Determine the slope (b) of the line: You Answered .382 4.25 5 .509 Correct Answer .235
