Six subjects have their blood pressures recorded. After twelve weeks on the medication, the same six subjects have their blood pressure recorded again. For this test, only systolic pressure is of concern. Test at the 1% significance level. (Calculate "after" - "before.")

[8/12 Points] PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER The weighls of eight rowers on each of the Cambridge and Oxford crew teams are given here. Assuming that these men represent appropriate random samples, test the hypothesis that the mean weight of rowers on the Cambridge and Oxford crew teams are equal versus the alternative that they are not equal. Cambridge: 188.0, 183.0, 194.5, 185.5, 214.5, 203.0, 186.5, 178.0 Oxford: 186.0, 184.5, 204.5, 184.0, 195.0, 202.0, 174.5, 183.0 To determine which ttest to use, nd the standard deviation for each sample.

There is not evidence to conclude that the populations of Cambridge and Oxford rowers differ with regard to mean weight. 5, We reject the null hypotheses. There is evidence to conclude that the populations of Cambridge and Oxford rowers differ with regard to mean weight. 7", We do not reject the null hypotheses. There is evidence to conclude that the populations of Cambridge and Oxford rowers differ with regard to mean weight. \"F, We reject the null hypotheses. There is not evidence to conclude that the populations of Cambridge and Oxford rowers differ with regard to mean weight.
