Question
Transcribed Image Text:The data below are the average one-way commute times (in minutes) for selected students and the number of absences for those students during the term. Find the equation of the regression line for the given data. What would
be the predicted number of absences if the commute time was 95 minutes? Is this a reasonable question? Round the predicted number of absences to the nearest whole number. Round the regression line values to the nearest
hundredth.
Commute time (min), x 72 85 91 90 88 98 75 100 80
3 7 10 10 8 15 4 15 5
Number of absences, y
O A. y=0 45x + 30 27, 73 absences; Yes, it is reasonable.
O B. y=0.45x-30.27; 12 absences; No, it is not reasonable. Ninety-five minutes is well outside the scope of the model.
O C. =0 45x + 30 27; 73 absences; No, it is not reasonable. Ninety-five minutes is well outside the scope of the model,
OD. y 0 45x-30 27; 12 absences; Yes, it is reasonable.
