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 20 mm Hg. (b)Suppose that the researcher decides not to reject the null hypothesis. What sort of error might he be making? (c)Suppose the true mean systolic blood pressure of CEOs of major corporations is  mm Hg. Fill in the blanks to describe a Type I error. A Type I error would be rejecting/failing to reject the hypothesis that u is
