Can someone answer the MX= MY= SDx= and SDy=

typically dealing with "perfect correlati confidence intervals. We cover this "ERROR" later. Here is a set of (x,y) data to be used below: Student Hours Final Points 1 10 65 THE FORMULA FOR A REGRESSION LINE IS: Y' = bX + a 2 20 85 Where Y' is the predicted point total based on the regression equation 12 70 which has a slope, "b", and a y-intercept, 4 25 93 5 15 75 HERE IS THE EQUATION: SLOPE (b) = E/ (x - Mx ) * (y - My ) ] / E(x - Mx )2 6 9 50 22 90 1. Calculate the MEAN (M) and the Standard Deviation (SD) for BOTH the x and y values: 8 14 78 9 16 80 Mx = ; My = ; SDx = ; SDy = 10 10 99
