Part 1. Student commute modal split

Yes

90

A brief description of the method(s) used to gather data about student commuting:

Students that are not travelling with a car with only the driver in the car are assumed to be travelling sustainably. This is determined by letting p=0.1 be the fraction of students who possess a student parking permit, which is determined by the empirical fraction of students who have a parking permit. Then, 1-p=0.9 yields the fraction of students who are travelling sustainably.
