Arthur wanted to investigate how the amount he exercises impacts his weight loss. Each week he recorded the number of hours he exercised and the amount of weight he lost that week (in kilograms). Exercise (hours) 1 2 3 4 5 Weight lost (kg) 0.86 1.13 1.59 2.27 2.62 All of the scatter plots below display the data correctly, but which one of them displays the data best? By convention, a good scatter plot uses a reasonable scale on both axes and puts the explanatory variable on the x-axis.
