A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He has good Peasor believe that the mean systolic blood pressure, µ, of CEOS of major corporations is more than 134 mm Hg, which is the value reported in a possibly outdate 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 mean of the sample to be 146 mm Hg and the standard deviation of the sample to be 16 mm Hg. Based on this information, complete the parts below. (a) what are the null hypothesis H, and the alternative hypothesis H, that should be used for the test? ロ<ロ OSO ロ H :0 ロ=ロ (b) Suppose that the researcher decides not to reject the null hypothesis. What sort of error might he be making? (Choose one) ▼ (c) Suppose the true mean systolic blood pressure of CEOS of major corporations is 134 mm Hg. Fill in the blanks to describe a Type I error. A Type I error would be (Choose one) v the hypothesis that u is (Choose one) (Choose one) ▼ when, in fact, u is (Choose one)

Question
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blood pressure, u, of CEOS of major corporations is more than 134 mm Hg, which is the value reported in a possibly outdated journal article.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 146 mm Hg and the standard deviation of the sample to be 16 mm Hg. Based on this information, complete the parts below. (a) what are the null hypothesis H, and the alternative hypothesis H, that should be used for the test? Ho OSO H, : ロ=ロ (b) Suppose that the researcher decides not to reject the null hypothesis. What sort of error might he be making? (Choose one) ▼ (c) Suppose the true mean systolic blood pressure of CEOS of major corporations is 134 mm Hg. Fill in the blanks to describe a Type I error. A Type I error would be (Choose one) v the hypothesis that u is (Choose one) (Choose one) ▼ when, in fact, u is (Choose one)
