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?

Question 9 (1 point)
It is reported in USA Today that the average flight cost
nationwide is $595.711. You have never paid close to that amount
and you want to perform a hypothesis test that the true average is
actually greater than $595.711. The hypotheses for this situation
are as follows: Null Hypothesis: μ ≤ 595.711, Alternative
Hypothesis: μ > 595.711. A random sample of 30 flights shows an
average cost of $584.559 with a standard deviation of $59.3656.
