Do women and men differ in how they perceive their life expectancy? A researcher asked a sample of men and women to indicate their life expectancy. This was compared with values from actuarial tables, and the relative percent difference was computed. Perceived life expectancy minus life expectancy from actuarial tables was divided by life expectancy from actuarial tables and converted to a percent. The data given are the relative percent differences for all men and women over the age of 70 in the sample. Men −28 −24 −21 −22 −15 −13 Women −22 −20 −17 −9 −10 −11 −6 Use technology to approximate the ???? distribution for this test. Do NOT use the conservative approach. What is the test statistic ???? ?
