A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He believes that the mean systolic blood pressure, µ, of CEOs of major corporations is different from 136 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistics test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 144 mm Hg and the standard deviation of the sample to be 20 mm Hg.
