Suppose you would like to analyze the effect of smoking
cigarettes on life expectancy, using the simple linear regression
model of lifeyrs=β0+β1smoke+μlifeyrs=β0+β1smoke+μ where
lifeyrs is number of years lived and smoke is pack of cigarettes
smoked. Which of the following factors are most likely correlated
with the life expectancy and thus are included in the error
term μμ?
I. Other
drug use
II. Exercise
habits
III. Diet
IV. Alcohol abuse
a.
I, II, III.
b.
II, III.
c.
I, II, III, IV.
