The data is given as follow. Xi 2 6 9 13 20 ?? 7 18 9 26 23 The estimated regression equation for these data is Y = 7.6 +.9x. Compute SSE, SST, and SSR (to 1 decimal). SSE SST III SSR What percentage of the total sum of squares can be accounted for by the estimated regression equation (to 1 decimal)? % What is the value of the sample correlation coefficient (to 3 decimals)?
Expert Answer
Consider the given data. xi 2 6 9 13 20 yi 7 18 9 26 23 The estimated regression equation is obtained as . The formulae for SSE, SST, SSR are defined as follows: Find the mean of using the formula defined as . Here is the sum of observations of y and
