A doctor claims that the average jogger’s maximal oxygen uptake is greater than the average of all adults. A random sample of 15 joggers has a mean of 40.6 millimeters per kilogram (ml/kg) and a standard deviation of 6 ml/kg. If the average of all adults is 36.7 ml/kg, is there enough evidence to support the doctor’s claim? Conduct a t-test; use a significance level of α = 0.05 and a critical value of 2.086. What is the sample average?
