16. In a study, nine tires of a particular brand were driven on a track under identical
conditions. Each tire was driven a particular controlled distance (measured in
thousands of miles), and afterward the tread depth was measured. Tread depth iS
measured in "mils." Here, 1 mil is 0.001 inch. The least-squares regression line was
computed, and added to a scatterplot of these data. On the plot, one data point iS
marked with an "X". This data point will be referenced in Question 15.
