X 16. Use the table below to explore the relationship between the two variables x and y. A statistician performed a linear regression and plotted the residuals. Based on the residual plot, the statistician decided to exclude one point. The statistician then performed linear regression on the remaining points. The result was a new line fit more closely than the original. Which point was excluded? * yl 2.5 12 4.2 14.2 5.6 16.2 6.7 18.1
