You are conducting some behavioral research on the house mouse Mus musculus. Specifically, you want to see how noise affects their ability to complete a task, in this case running through a small maze to reach a reward (an apple slice). You have a group of 20 mice, and you run each of them through a maze under 4 different noise conditions: no noise, low-level noise, moderate-level noise, and high-level noise. You record the time (in seconds) it takes the mouse to reach the apple slice, and obtain these data.
