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blood pressure, H, of CEOS of major corporations is less than 132 mm Hg, which is the value reported in a possibly outdated journal article.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 be 124 mm Hg and the standard deviation of the sample to be 18 mm Hg. Based on this information, answer the questions below. What are the null hypothesis (H) and the alternative hypothesis (H,) thất should be used for the test? Hu is ? His 2 In the context of this test, what is a Type II error? A Type II error is ? v the hypothesis that u is ? vwhen, in fact, u is ? Suppose that the researcher decides not to reject the null hypothesis. What sort of error might he be making? ?
