1 example 1 Life Span Chapter 5.7 The data in Table 5.25 show the expected life span of people for certain birth years in the United States. A technology-determined logistic function for the life-span data is where x is the number of birth years after 1900. The graph of this logistic function is shown below. Use this model to a.Estimate the expected life span of a person born in the United States in 1955 and a person born in 1980. b.Find an upper limit for a person’s expected life span according to this model. y x  2009 PBLPathways
