Hebelieves that the mean systolic blood pressure, u, of CEOS of major corporations is more than 136 mm Hg, which is the value reported in apossibly outdated journal article. He plans to perform a statistical test and measures the systolic blood pressures of a random sample of 150CEOS of major corporations.Suppose that the population of systolic blood pressures among CEOS of major corporations has a standard deviation of 16 mm Hg and that theresearcher performs his hypothesis test using the 0.01 level of significance.Based on this information, answer the questions below. Carry your intermediate computations to at least four decimal places, and round yourresponses as indicated.(If necessary, consult a list of formulas.)
