least squares regression equation

Question

Compute the least squares regression equation of y on x and x on y for the following data what is the regression coefficient and what does it mean?

X=  5 6 8 10 12 13 15  16 17

Y= 16 19 23 28 36 41 44  45 50

find the predicted value of Y for X = 7 9 19 18 20

Answer 1

Arroj Riaz, hello

I used the Least Square Method on my TI-84 calculator.

Regression Equation:  y = 2.83x + 1.47

y(7) = 21.287

y(9) = 26.95

y(18) = 52.43

y(19) = 55.26

y(20) = 58.1
