A study of the effects of exercise used rats bred to have high or low capacity for exercise. The 8 high-capacity rats had mean blood pressure 89 mm Hg and standard deviation 9 mm Hg; the 8 low-capacity rats had mean blood pressure 105 mm Hg with standard deviation 13 mm Hg. We suspect that rats with low capacity for exercise tend to have a higher blood pressure than rats with a high capacity for exercise. To see if this is true, test these with hypotheses for the mean blood pressure of all rats with high capacity (HC) and all rats with low capacity (LC) for exercise: H0 : μ HC = μ LC versus HA : μ HC < μ LC H0 : μ HC = μ LC versus HA : μ HC > μ LC H0 : μ HC = 89; HA : μ LC = 105 versus H0 : μ HC ≠89; HA : μ LC ≠105 H0 : μ HC = μ LC versus HA : μ HC ≠μ LC

A study of the effects of exercise used rats bred to have high or low capacity for exercise. There were 14 high-capacity and 18 low-capacity rats. To compare the mean blood pressure of the two types of rats using the conservative Option 2 t-procedures. What are the associated degrees of freedom
