Question
For the following two questions, use the following information. We have three equations. They are (1) Weight = a_1 + 6(Height); 2) Weight - a_2 + 5(Height) + 22(Sex). Where Sex = 0 if female. 1 if male, and (3) Weight - 150 + 35(Sex). In equation 3. what is the 150 telling us? (I know it is the intercept; don't tell me that.) The coefficient 6 in equation one is one unit larger than the 5 in equation 2. Why is it larger? Whit is it taking into account? Explain the meaning. Don't describe the path.Explanation / Answer
Answer:
a).
150 is the estimated weight when the person is female.
b).
The coefficient for Height in equation 1 is larger because it is not considering gender of the person separately.
Equation 2 to taking account of gender, so coefficient for Height in equation 2 is smaller, gender effect is added separately.
