Hello i need answers/help with these 4 questions. This is business calc. Thank you so much!

Compute the sum-of-squares error (SSE) by hand for the given set of data and linear model. HINT [See Example 1 (0, 1), (1, 3), (2, 4), (5, 0); y--x 2 SSE Need Help?

Explanation / Answer

1)

SSE =14)

2)a)

b)

3)

b1 =Sxy/Sxx =0.7308

and b0 =ybar -b1*xbar =2.0385

hence y(x) =0.7308x+2.0385

5)

f(r) =0.135x+3.15

hence at 70% level; number of jobs =0.135*70+3.15 =12.6

X Y Yi'=b0+x*b1 (Y-Yi')^2 0 -1 2.0000 4.0000 1 3 1.0000 1.0000 2 4 0.0000 0.0000 5 0 -3.0000 9.0000 SSE 14.0000
