Unformatted text preview: Time = 8.84 + 0.940(7) Time = 8.84 + 6.58 Time = 15.42 Average time for students living 7 miles from school is 15.42 minutes to get to school. 8) The y intercept is 8.84 and the slope of the line is 0.940 / 1. The slope equals the change in y over the change in x, or the change in time / the change in distance. There are a couple of outliers that lie far from the best fit line. The population is all MCC students but the sample size is the MTH 160H class of 16 students. Although the data has a positive correlation it is very weak because it is 0.664, it would be much stronger if some of the outliers were absent. The line of best fit could be very useful if a MCC student wanted to calculate an average time to leave their house in the morning to get to school on time....
