A national business magazine reports that the mean age of retirement for women executives is 62.7. 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 97 recently retired women executives and found that they had a mean age of retirement of 63.1. Assuming the population standard deviation is 4.0 years, is there sufficient evidence to support the organization’s belief at the 0.10 level of significance? Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. H0Ha: μ=62.7: μ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯62.7
