Classify the linear correlation.$($b$)$ Identify the outlier.$($c$)$ After excluding the outlier, the equation of the line of best fit is y $=0\mathrm{.}92$x $-9\mathrm{.}61$ and the correlation coefficient is $0\mathrm{.}76.$ Compute each residual using above equation with the outlier excluded, and then plot the residuals. What do you think about the residuals?$($d$)$ Do the results suggest that the number of books a student reads depends on the student's age? Explain.
