Question 2 Try to guess within 30 seconds. Check your guess with your friends. Number of students in your school who travel to school by bus: a. More than 200 b. Less than 200Answer: a. More than 200 (This depends heavily on the school's size) Method: I would estimate the total number of students in the school and then estimate the percentage that use the bus. Assuming a large school has about 1,200 students. Assuming about 30% of them use the bus service. Estimate: 30% of 1,200 = 360 students, which is more than 200.
