Math Problem Statement
nterpret the y-intercept. Select the correct choice and, if necessary, fill in the answer box to complete your choice. A. For a commute time of zero minutes, the index score is predicted to be enter your response here. (Round to three decimal places as needed.) B. For every unit increase in commute time, the index score falls by enter your response here, on average. (Round to three decimal places as needed.) C. For every unit increase in index score, the commute time falls by 69.042, on average. (Round to three decimal places as needed.) D. For an index score of zero, the commute time is predicted to be enter your response here minutes. (Round to three decimal places as needed.) 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.
