Bivariate data obtained for the paired variables x and y are shown below, in the table labelled "Sample data." These data are plotted in tho scatter plot in Figure 1, which also displays the least-squares regression line for the data. The equation for this line is y25.35+1.10x In the "Calculations" table are calculations involving the observed y values, the mean y of these values, and the values y predicted from the regression equation Sample data Calculations 215.4 210.7 237.7 251.7...
