Below are bivariate data giving birthrate and life expectancy information for each of twelve countries. For each of the countries, both x, the number of births pe one thousand people in the population, and y, the female life expectancy (in years), are given. Also shown are the scatter plot for the data and the least-square regression line. The equation for this line is y = 81.93 -0.47x. Birthrate, x Female life expectancy, y (number of births per 1000 people) (in years) 53.1 59.6 49.9 60.5 27.2 72.3 18.3 71.3 34.7 66.1 (in years) Female life expectancy 14.6 76.2 * x 32.4 64.3 49.1 54.9 47.8 57.1 24.0 73.8 14.9 72.5 Birthrate 38.8 64.9 (number of births per 1000 people) Based on the sample data and the regression line, complete the following. (a) For these data, birthrates that are greater than the mean of the birthrates tend to be paired with female life expectancies that are (Choose one) |the mean of the female life expectancyes. reater than (b) According to the regression equation, rot an increase of one (birth per 1000 people) in birthrate, there is a corresponding decrease of how many years in female life expectancy?
