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

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
