For a linear regression problem, The actual observed y-value when x = 3 is y = 11. The least squares line is ? = 2x+3. The predicted value when x=3 is ? = 9. Determine the value of the residual (prediction error) Cannot be determined from the information given residual = 2 residual = 11 residual = 9

The regression line for the given data is Y = -1.885x + 0.758. Determine the residual of a data point for which X = -1 and Y = 3.

Suppose a sample regression equation is given by y = 11 - 0.80x. What is the predicted value of y and residual when x is 3 and y is observed to be 9? Choose 1: y = 8.6, residual = 0.4; y = 9.4, residual = -0.4; y = 9, residual = 0.4; y = 9, residual = -0.4.

Find the least squares regression line for the points. Use the regression capabilities of a graphing utility or a spreadsheet to verify your results. Then plot the points and graph the regression line. $$ (-2,4),(-1,1),(0,-1),(1,-3) $$
