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 population average?

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.70 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level?

To help assess the health risks of second-hand smoke, the levels of cotinine (a metabolite of nicotine) were measured in mmol/l in the urine of seven subjects prior to exposure to second-hand smoke and shortly after a two-hour exposure to secondary cigarette smoke. Did the exposure significantly increase the cotinine level? Assume cotinine levels are not normally distributed and analyze with an appropriate sign test.
