The data below represent commute times (in minutes) and scores on a well-being survey. Complete parts (a) through (d) below. Commute Time (minutes), x Well-Being Index Score, y 20 25 35 60 105 O 66.2 64.1 72 69.3 68.1 67.6 67.2 66.1 (Round to three decimal places as needed.) O D. For every unit increase in index score, the commute time 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 (c) Predict the well-being index of a person whose commute time is 30 minutes. The predicted index score is (Round to one decimal place as needed.) (d) Suppose Barbara has a 15-minute commute and scores 67.6 on the survey. Is Barbara more "well-off" than the typical individual who has a 15-minute commute? Se complete your choice. (Round to one decimal place as needed.) O A. Yes. Barbara is more well-off because the typical individual who has a 15-minute commute scores O B. No. Barbara is less well-off because the typical individual who has a 15-minute commute scores
