Please answer both parts (1 and 2), thank you.

2 MC Practice #2 MC Practice #1 A scatterplot displays the relationship between reaction Which of the following is a true statement regarding time (in seconds) and distance needed to stop a car (in Residual Plot the residual plot shown here? feet). If stopping distance were measured in yards 100 F instead of feet, how would the correlation r between Since the residual plot shows a random scatter of points, a reaction time and stopping distance change? 50 linear model is appropriate. 20 L Or would be multiplied by 12 Since the residual plot shows a random scatter of points, a -20 linear model is not appropriate. Or would be multiplied by 3 residual -60 -100 The residual plot shows that the original data has a weak Or would not change 9 11 13 15 17 19 relationship. Or would be divided by 3 tree age (years) Or would be divided by 12
