The regression line formula is ___.- Y’= bX + a The simplest way to place a regression line on a scatterplot is to- predict Y-values based on two X-values from the X-axis If Pearson’s r is -1.00, prediction will be- strong Multiple regression is used when we have- more than one predictor in an equation In the prediction equation, which symbol is not replaced with a value until we predict a value on Y?- X Which of the following is not needed when calculating error?-b...
