A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He has good reason to believe that the mean systolic blood pressure,

, of CEOs of major corporations is different from134

mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be146

mm Hg and the standard deviation of the sample to be16

mm Hg.

Based on this information, complete the parts below.
