Question 1

x = 27

y =267

^x2 =151.5

^y2 = 14 509

xy = 1406.5

Sample size (n) = 6

1. If the least squared method is used to estimate the regression equation relating x and y, calculate the slop coefficient ?

Question 2

x = 34.5

y =312

^x2 =207.75

^y2 = 16534

xy = 1744

Sample size (n) = 5

1. If the least squared method is used to estimate the regression equation relating x and y,what is the sum of squares due to regression (SSR)?
