Twenty plots, each 10 by 4 meters; were randomly chosen in a large field of corn: For each plot; the plant density (number of plants in the plot; X) and the mean corn cob weight (in grams of grain per cob, Y) were observed and the following summary statistics are obtained from the study: 128.05, Ox = 32.61332, Vy = 224.10, Oy = 24.95448, R = 0.9418 Calculate the regression equation for this dataset Y = 403.882 1.231 Y = 403.88 + 1.231 Y = -316.3762 + 0.7206 Y = 316.3762 + 0.7206 Y = 316.3762 0.7206
