Teacher instructions is to use the a and b formulas while also rounding to the nearest thousandth.

How would I do this in depth? The only thing I figured out was the chart which was correct.

1. Calculate the regression coefficients (a and b) for predicting exam grades (1). SHOW ALL YOUR WORK and remember to round all work to the thousandths place. (3 points) m. What is the regression equation for predicting exam grades (Y) from known number of hours worked (X)? (1 points) n. What would you predict a student's exam grade (Y) would be if be she worked 6 hours per week (? - SHOW ALL YOUR WORK. (1 point) o. Calculate the standard error of estimate for predicting exam grades (1)- SHOW ALL YOR WORK (2 points)= 2. cey C1005 completed table his student who(X ) exam X 2 grades Xy 30 14 900 2 420 25 49 ITS 4 127 Ice 729 108 12 14 4 - 6 V s w 312 32 4 15 25 6 2 8.8 22 225 484 28 330 3 ce 12 784 20 44 400 3 29 240 9 LO 841 87 T= 10 ex= 129 208 By: 219 EX3 Ey ? 244 3 Exy = 5135 23 3
