Question: Example gave the weights of eight rowers on each of the Cambridge and Oxford crew teams. The weights are shown again here. Assume that these men represent appropriate random samples from the population of members of these crew teams over all time. Test the hypothesis that the mean weights of the populations of rowers on the Cambridge and Oxford crew teams over all time are equal versus the alternative that they are not equal. Specify the value of a that you chose to use.
Cambridge: 188.5, 183.0, 194.5, 185.0, 214.0, 203.5, 186.0, 178.5
Oxford: 186.0, 184.5, 204.0, 184.5, 195.5, 202.5, 174.0, 183.0
Example: Tiny Boatmen Here are the weights (in pounds) of 18 men who were on the crew teams at Oxford and Cambridge universities (The Independent, March 31, 1992; also Hand et al., 1994, p. 337):
Cambridge: 188.5, 183.0, 194.5, 185.0, 214.0, 203.5, 186.0, 178.5, 109.0
Oxford: 186.0, 184.5, 204.0, 184.5, 195.5, 202.5, 174.0, 183.0, 109.5
