Question
Suppose we are interested in examining the relationship between AGE and FEV among children. We construct the following model:
FEVi = 0 + 1 AGEi + i
What does 0 represent?
the mean FEV of newly born children
the mean FEV of children whose age is the mean age in the data
the FEV of a newly born child
the FEV of a child whose age is the mean age in the data
a.the mean FEV of newly born children
b.the mean FEV of children whose age is the mean age in the data
c.the FEV of a newly born child
d.the FEV of a child whose age is the mean age in the data
Explanation / Answer
If Age=0
Fev= 0 + 1*0= 0
Hence for Age=0, FEV= 0
Hence 0 represents the FEV of a newly born child
