The value of cov(x,y) is ( Note that what excel gives you in a covariance matrix is population covariance and here you need sample covariance. When you get covariance from the excel matrix, multiply it by n and divide by n-1 to get sample covariance. ): -2712511.08 . Then, 5. The value of b 1 is -0.062315477 . 6.
