The National Center for Health Statistics reports that the mean systolic blood pressure for males 35 to 44 years of age is 128. Do the executives of a large company have a different mean blood pressure? We collect data on 72 executives and find x-bar=126.07 and s=15. For this test, we plan to use a significance level of 0.05.

1. Using a calculator, conduct the appropriate hypothesis test. Report the p-value.

2. Based on the p-value found in the previous question, make a decision and interpret the results in context.

3. If you made an error with your decision what type of error could you have made? What would this mean in context?

4. Explain the power of this test in context

1. The National Center for Health Statistics reports that the systolic blood pressure for males (35-44 years of age) has a mean 128 and standard deviation 15. The medical director of a large company looks at the medical records of 105 executives in same age group and finds that the mean systolic blood pressure in this sample is 126.30. At 95% level, is this evidence that the company’s executives have a lower mean systolic blood pressure than the general population?
