For a pair of sample x- and y-values, the _______ is the difference between the observed sample value of y and the y-value that is predicted by using the regression equation.
A sample regression equation is given by y=-100+ 0.5x. If x = 20, the predicted value of yis. ο ο ο ο < Prey 6 of 30 !!! Next >

In regression analysis, a careful study of the differences, y-y between observed and estimated y values, given x (in order to decide whether crucial assumptions are fulfilled that allow valid inferences about the true regression line to be made from an estimated regression line) is called residual analysis. True or False
