36 67.2 46 66.9 73 66.6 97 63.5 ..... (a) Which variable is likely the explanatory variable and which is the response variable? O A. The explanatory variable is commute time and the response variable is the well-being score because well-being score affects the commute time score. B. The explanatory variable is the well-being score and the response variable is commute time because commute time affects the well-being score. OC. The explanatory variable is the well-being score and the response variable is commute time because well-being score affects the commute time. D. The explanatory variable is commute time and the response variable is the well-being score because commute time affects the well-being score. (b) Draw a scatter diagram of the data. Which of the following represents the data? O A. В. Oc. OD. 70- 70- 110- 110- 604 0- 60 Time (min) 110 110 70 60 70 Score Time (min) Score (c) Determine the linear correlation coefficient between commute time and well-being score. r= (Round to three decimal places as needed.)
