Identify the equation of the least squares regression line that most

closely matches the data set.

yˆ = 0.17x - 13.2

yˆ = 5.5x + 52

yˆ = 3.5x - 6921.2

yˆ = - 2.2x + 13.8

The answer is yˆ = 5.5x + 52

The closest to this is that equation, you can check it to prove that it is closer than the other options.

Let, yˆ = 5.5x + 52 be the equation

X=2,4,6,8,10

y=?

x1=2

y1=5.5 (2) + 52

=63

x2=4

y2=5.5 (4) + 52

=74

x3=6

y3=5.5 (6) + 52

=85

x4=8

y4=5.5 (8) + 52

=96

x5=10

y5=5.5 (10) + 52
