A sample of eight vehicle owners was taken to estimate the demand for vehicle on the weekly price of fuel. The demand for vehicles per month is (X) and the price of fuel per week in $ is (Y)

Calculate the x^2, predicted y, residuals, SSE, SSR, SST? The values of x and y are given below:

Obs.: 1 2 3 4 5 6 7 8

X : 5 3 7 9 2 4 6 8

Y : 20 23 15 11 27 21 17 14
