a. Fit a regression line of Y on X.
b. Prepare a table of predicted values and residuals.
Mean daily Score(Y)
34 39 30 33 36 38 45 41 48

You can put this solution on YOUR website! A company recruits personnel for its sales department on the basis of special tests designed to judge the potential of the candidates. The following table gives test scores and the mean daily sales for 9 executives.
a. Fit a regression line of Y on X.
Y = 0.548326x+1.849949
------------------------
b. Prepare a table of predicted values and residuals.
To do that substitute your X-values into the regression line equation
to get the predicted Y-values.
------
To find the residual values find the difference (0-P) between the
Y values listed below and the predicted Y-values; do that for each
X value.
