Shoe Size | Height (inches)

7.5 66

8 67

8 68

10 71

10.5 70

11 73

a) Letting the variable x represent shoe size and y represent height, determine the least squares regression line and correlation coefficent.

b) Based on the correlation coefficient calculated above, can the least squares regression line be confidently used as a predictor of height? Why or Why not?

Please help show work.
