Elementary school students were given a geometry assignment. They were to measure the area of several rectangles and to measure the diagonal of the rectangle as shown in the table. The equation of the least-squares regression line û = 3.6 + 0.113x, where û is the diagonal and x is area of the rectangle. Which shows the residual plot Area (in) 24 53 46 5 78 100 84 Diagonal (in.) 4.472 6.928 10.296 9.592 3.162 12.490 14.142 12.962 ​
