Given are five observations for two variables, 2 and y. SSE SST 0.16 70 a * * 1 Yi 3 The estimated regression equation for these data is ŷ = 0.9 +2.5x. a. Compute SSE, SST, and SSR using the following equations (to 1 decimal). | SSE = Σ (y – 5,) - SST = (y - y)² SSR=(9-7)² 2 Does this least squares line provide a good fit? Yes, the least squares line provides a very good fit c. Compute the sample correlation coefficient (to 4 decimals), * 7 SSR 68 b. Compute the coefficient of determination r² (to 3 decimals). 3 A 8 4 5 10 14
