Bivariate data obtained for the paired variables \( x \) and \( y \) are shown below, in the table labelled "Sample data." These data are plotted in the scatter plot in Figure 1, which also displays the least-squares regression line for the data. The equation for this line is \( \hat{y}=89.86+0.67 x \). In the "Calculations" table are calculations involving the observed \( y \) values, the mean \( \bar{y} \) of these values, and the values \( \hat{y} \) predicted from the regression equation. Sample data Answer the following:
