The diastolic blood pressure for American women ages 18 to 44 has an approximately Normal distribution with mean = 75 mm Hg. We suspect that regular exercise will lower the blood pressure. A sample of 25 women who jog at least 5 miles per week gives sample mean blood pressure of 71 mm Hg and standard deviation of 10 mm Hg. Is this good evidence that the mean diastolic blood pressure for the population of regular exercisers is lower than 75 mm Hg?
