Given the following relationship:
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 representheight, determine the least squares regression line and correlationcoefficent.
b) Based on the correlation coefficient calculated above, canthe least squares regression line be confidently used as apredictor of height? Why or Why not?
Please help show work.
