Question

Might we be able to predict life e 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 per one thousand people in the p and y, the female life expectancy (in years), are given. Also shown are the scatter plot for the data and the least- squares regression line. The equation for this line is y 82.39-0.49x. 52.0 57.5 25.8 72.3 30.9 14.3 40.1 48.0 72.0 64.5 66.1 s0.2 14.1 53.6 to Excel Based on the sample data and the regression line, answer the following 1. Fill in the greater than the mean of the female life expectancies tend to be paired Choos one the mean of the birthrates thngng decrease of how birthrate was 18.7 births per 1000 people? expectancy (in years) when the birthrate is 18.7 births per 1000

Explanation / Answer

From the given regression equation:

1) Less than

2) Corresponding decrease = Slope = 0.49

3) Observed value = 74

4) Predicted value = 82.39 - 0.49*18.7 = 73.2
