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. On each day you measure how many minutes of each hour they spend 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?

As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.
