IMR and Life Expectancy. From the International Data Base, published by the U.S. Census Bureau, we obtained data on infant mortality rate (IMR) and life expectancy (LE), in years, for a sample of 60 countries. The data are presented on the WeissStats site.

For the estimations and predictions, use an IMR of 30. For the correlation test, decide whether IMR and life expectancy are negatively linearly correlated.
