5 Plot the regression line with a minimum of 4 data points. To plot the line, we can use two points. We can use the mean values (X, Y) as one point, and then calculate a predicted Y value for another X value. Point 1: (X,Y) = (58.625, 66.5) Let's choose X = 20. Ypredicted = 25.6446 + 1.5726 x 20 = 25.6446 + 31.452 = 5.8074 Point 2: (20, 5.8074) Let's choose X = 90. Ypredicted = 25.6446 + 1.5726 x 90 = 25.6446 + 141.534 = 115.8894 Point 3: (90, 115.8894) Let's choose X = 40. Ypredicted = 25.6446 + 1.5726 x 40 = 25.6446 + 62.904 = 37.2594 Point 4: (40, 37.2594) The regression equation is approximately Y = 25.64 + 1.57.X
