A national business magazine reports that the mean age of retirement for women executives is 63.2. A women's rights organization believes that this value does not accurately depict the current trend in retirement. To test this, the group polled a simple random sample of 78 recently retired women executives and found that they had a mean age of retirement of 64.2. Assuming the population standard deviation is 4.4 years, is there sufficient evidence to support the organization's belief at the 0.02 level of significance? Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho :u = 63.2 63.2
