You put n = 20 rats in a cage that is in a room with a 65-degree temperature. The next day you put them in a cage with a 70-degree temperature. On the final day of the study you put them in a cage with a 75-degree temperature. For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel. To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do?
