Suppose you are interested in the relationship between educational attainment (measured by years of completed schooling) and the how long people live (measured by age at death in years). For a sample of 100 recently-deceased people, you collect information on their educational attainment and their age at death. Treating educational attainment as the independent variable (X) and age at death as the dependent variable (Y), you compute the following regression equation.
Suppose you are interested in the relationship between educational attainment (measured by years of completed schooling) and the how long people live (measured by age at death in years). For a sample of 100 recently-deceased people, you collect information on their educational attainment and their age at death. Treating educational attainment as the independent variable (X) and age at death as the dependent variable (Y), you compute the following regression equation.
Y = 55 + 2.0X + e
a) Interpret in words this equation. That is, what do each of the numerical values in the equation tell us? Be specific.
b) How long would you predict that someone with a college education (that is, someone with 16 years of schooling) will live?
