Question
Suppose the weights (in pounds) of eight rowers on each of the Cambridge and Oxford crew teams are given below. 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. (Let population 1 be the Cambridge team and population 2 be the Oxford team. Use ? = 0.05.)
- Cambridge: 188.0, 182.5, 195.0, 185.5, 214.5, 204.0, 186.5, 178.0
- Oxford: 186.5, 185.0, 204.5, 185.0, 195.0, 202.0, 173.5, 182.5
State the null and alternative hypotheses (in pounds). (Use Cambridge − Oxford. Enter != for ≠ as needed.)
