Question: 9 1 mark the distribution of systolic blood pressure for...

Question details

9. (1 mark) The distribution of systolic blood pressure for a population of adult males is Normal with σ-15. A SRS of 49 adult males is taken from this population and systolic blood pressure is measured for each man. A test of the hypothesis H0: μ 120 versus Ha: μメ120 rejects H0 at the 5% level if z--1.960 or z 〉 1.960 (in other words when |z > 1.960) where T120 15/V49 round your answer to at least 3 decimal places) 10. (1 mark) Suppose you are testing the hypothesis: What is the power of this test against the alternative 11-126 (if applicable, please Ho: μ 200 versus Ha: μ< 200 where the sample size is n - 16 and where the population is assumed to have a Normal distribution with σ-8. A 10% significance test rejects Ho if z <-1.282 where x-200 8/V16 What is the power of the test against the alternative μ round your answer to at least 3 decimal places) 195 (if applicable, please
