Question

Problem 1: A physician claims that joggers' maximal volume oxygen uptake is greater than the average of all adults. A sample of 15 joggers had a mean oxygen uptake of 40.6 millimeters per kilogram (ml/kg) and a standard deviation of 6 ml/kg. If the mean oxygen uptake for all adults is 36.7 ml/kg, is there enough evidence to support the physician's claim at a 10% significance level? Assumption: parameter: null hypothesis Ho: alternative hypothesis Hj: test statistic: rejection region: calculated test statistic: conclusion: p-value: d.f.) 0.25 0.10 0.05 0.025 0.01
