Rats in Space Researchers at NASA wanted to judge the effects of spaceflight on a rats tibia. The following data represent the length (in millimeters) of the right tibia upon return from the Spacelab Life Sciences 2 flight for a flight (experimental) group and ground (control) group of six rats each. Experimental Group Control Group 36.05 34.58 34.93 34.41 35.57 34.20 34.68 34.42 35.57 34.73 34.20 34.93 Source: NASA Life Sciences Data Archive Does the evidence suggest that the median tibia length in the experimental group is greater than the median tibia length in the control group at the a = 0.1 level of significance?
