14. According to the US Department of Health, the average life expectancy from birth for males in the United States may be modeled by the function(x) = 27x + 48.3, where x is the number of years since 1900. Using the model estimate the average life expectancy of a male who was born in 1985. (a) 85 (b) 71 (c) 70 (d) 75 What value of k would make the table a function? a) 5 (b) 1 (c) 3 (d)-2
The table below shows the life expectancy for an individual born in the United States in certain years. Year of Birth Life Expectancy CHART W NUMBERS IS BELOW Part (a) Decide which variable should be the independent variable and which should be the dependent variable. A)Independent: year of birth; Dependent: life expectancy Independent: life expectancy; B) Dependent: year of birth Incorrect: Your answer is incorrect.

The life expectancy at birth of both sexes in a particular year can be described by the function f(x)=11.51+ 14.71 ln x, where x represents the number of years after 1900. Use this function to determine the life expectancy in 2032.
The HDI does NOT include Select one: a. income. b. life expectancy. c. political freedom. d. education. e. health.
The life expectancy in Africa is 74 with a standard deviation of 8 years. A random sample of 49 individuals is selected. 1.What is the probability that the sample mean will be between 73.5 and 76 years? 2.What is the probability that the sample mean will be larger than 77 3.What is the probability that the sample mean will be less than 72.7 years?
The U.S. Center for Disease Control reports that the mean life expectancy was 47.6 years for whites born in 1900 and 33.0 years for nonwhites. Suppose that you randomly survey death records for people born in 1900 in a certain county. Of the 124 whites, the mean life span was 45.3 years with a standard deviation of 12.7 years. Of the 82 nonwhites, the mean life span was 34.1 years with a standard deviation of 15.6 years. Conduct a hypothesis...
We want to test is the life expectancy in country A and B are equal at 98% confidence level. Gven the A B Sample mean (years) 88 86 Sample standard deviation (years) 7.35 10.61 Sample size 27 35 Given the data in Exhibit 3, S is Select one: a. 1.2937 b. 3.3675 c. 2.6754 d. 2.2835
Insurance Companies track life expectancy information to assist in determing the cost of life insurance policies. Last year the average life expectancy of all policy holders was 77 years. ABI Insurance wants to determine if their clients now have a longer life expectancy, on average, so they randomly sample some of their recently paid policies. The ages of the clients in the sample are shown below. 86 75 83 84 81 77 78 79 79 81 76 85 70 76...
