Clare and Priya each took a random sample of 25 students at their school.
Clare asked each student in her sample how much time they spend doing homework each night. The sample mean was 1. 2 hours and the MAD was 0. 6 hours.
Priya asked each student in her sample how much time they spend watching TV each night. The sample mean was 2 hours and the MAD was 1. 3 hours.
a. At their school, do you think there is more variability in how much time students spend doing homework or watching TV? Explain your reasoning.
b. Clare estimates the students at her school spend an average of 1. 2 hours each night doing homework. Priya estimates the students at her school spend an average of 2 hours each night watching TV. Which of these two estimates is likely to be closer to the actual mean value for all the students at their school? Explain your reasoning.
