What should the correct answer have been and could you please explain the math/logic to reach that conclusion? Thank you.

Question 10 Here is a regression equation using 6882008 data. The independent variables are two reference group variables, one for blacks and one for others (those not white and not black). Therefore, whites are the reference group. The dependent variable is the number of siblings the respondent has. SIBLINGS = 3.36 + 1.61 (BLACK) + .87 (OTHER) If we had run a similar regression, but with blacks as the reference group, what would the resulting equation likely have looked like? '- SIBLINGS = 3.36 +1.61 (WHITE) + .87 (OTHER) 'SIBLINGS = 3.33 +1.31 (BLACK) + .87 (OTHER) SIBLINGS = 3.45 + 1.52 (BLACK) SIBLINGS = 4.97 1.61 (WHITE) - .74 (OTHER)
