Suppose the projections of male life expectancy at age 65 years in the United States are summarized in the following table (x = 0 corresponds to 2000).
| Year, x | 0 | 10 | 20 | 30 | 40 | 50 |
|---|---|---|---|---|---|---|
| Years beyond 65, y |
15.6 | 16.8 | 17.6 | 18.9 | 19.3 | 20.3 |
(a) Find an equation of the least-squares line for these data. (Round your coefficients to three decimal places.)
| y | = |
(b) Use the result of (a) to estimate the life expectancy at 65 of
a male in 2040. (Round your answer to two decimal places.)
years after 65
(c) Use the result of (a) to estimate the life expectancy at 65 of
a male in 2030. (Round your answer to two decimal places.)
years after 65

The life expectancy in the United States is 75 with a standard deviation of 7 years. A random sample of 49 individuals is selected. Round all probabilities to four decimal places. What is the probability that the sample mean will be larger than 77 years? Answer What is the probability that the sample mean will be within 1 year of the population mean? What is the probability that the sample mean will be within 2.5 years of the population mean?

According to the historical data, the life expectancy in the United States is less than or equal to the life expectancy in Ireland. A new study has been made to see whether this has changed. Records of 290 individuals from the United States who died recently are selected at random. The 290 individuals lived an average of 77.8 years with a standard deviation of 7.8 years. Records of 205 individuals from Ireland who died recently...

Suppose that you have in your possession bivariate data giving birthrate and life expectancy information for a random sample of 15 countries. For each of the countries, the data give both x, the number of births per one thousand people in the country's population, and y, the country's female life expectancy in years. The least squares regression equation computed from your data is y = 84.06 -0.51x. Suppose that you're predicting the female life expectancy for a country whose birthrate...

Life Insurance: A life insurance company wants to estimate the probability that a 40-year-old male will live through the next year. In a sample of 8000 such men from prior years, 7995 lived through the year. Use the relative frequency approximation to estimate the probability that a randomly selected 40-year-old male will live through the next year. Round your answer to 4 decimal places. P(he lives through the year) =
