Question

You take a sample of n = 50 rats and you put them in three different cages: On day 1, they are in a cage that is in a room with a 65-degree temperature. On day 2, they are in a cage with a 70-degree temperature. On day 3, they are in a cage with a 75-degree temperature. For each rat, you determine at which of the three temperatures they spent the most time running on their wheel. Then, for each different temperature, you determine the number of rats (the frequency of rats) that ran the most at that temperature. You discover the following frequencies: At 65 degrees, 22 rats ran the most of any day. At 70 degrees, 18 rats ran the most of any day. At 75 degrees, 10 rats ran the most of any day. You want to test a null hypothesis that says rats are equally likely to run the most at any of the three temperatures. What kind of hypothesis test should you do?
