According to the National Center for Health Statistics, the mean systolic blood pressure for males 35 to 44 years of age is 128. The health director of a large company wonders if this national average holds for the company's middle-aged male employees. So the director examines the medical records of a random sample of 72 male employees in this age group and records each of their systolic blood pressure readings. a) State an appropriate pair of hypotheses for a significance test in this setting. Be sure to define the parameter of interest. b) A 95% confidence interval for the mean systolic blood pressure of all 35- to 44-year-old male employees at this company is (126.43, 133.43). Based on this interval, what conclusion would you make for a test of the hypotheses in part (a) at the a=0.05 significance level?
