Consider the following sample data of X and Y:

X Y
8 22.3
6 16.71
9 25.21
6 15.84
1 2.75
8 21.22
2 5.27
1 2.32
10 27.39
7 19.35

a. Regress Y against X without any constraints. What is the regression equation? Predict Y when X = 10.

b. Force the regression line through the origin. What is the new regression equation? Predict Y when X 10 with this equation.

c. Force the regression line to go through the point (5, 13). What is the new regression line? What is the new regression equation? Predict Y when X = 10 with this equation.

d. Regress Y against X with the constraint that the slope must be less than or equal to 2. What is the new regression equation? Predict Y when X = 10 with this equation.
