Extracted text: The data below represent commute times (in minutes) and scores on a well-being survey. Complete parts (a) through (d) below. Que Commute Time (minutes), x Well-Being Index Score, y 5 15 30 40 69.0 67.8 66.3 65.5 63.9 62.6 60.3 60 84 105 O Interpret the y-intercept. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. For an index score of zero, the commute time is predicted to be minutes. (Round to three decimal places as needed.) O B. For every unit increase in index score, the commute time falls by , on average. (Round to three decimal places as needed.) O C. For a commute time of zero minutes, the index score is predicted to be (Round to three decimal places as needed.) O D. For every unit increase in commute time, the index score falls by , on average. (Round to three decimal places as needed.) O E. It is not appropriate to interpret the y-intercept because a commute time of zero minutes does not make sense and the value of zero minutes is much smaller than those observed in the data set (c) Predict the well-being index of a person whose commute time is 25 minutes.
