The indicator variable is defined as x = 1 if the house is within walking distance of an "A" rated public school and x = 0 if the house is NOT within walking distance of an "A" rated public school. If there was interaction in the regression problem, an appropriately fit regression model would have…?
a) A different slope and different y-intercept for those within walking distance and those not.
b) A different y-intercept for those that were within walking distance and those that were not; the slope would not change.
c) A different slope, but not a different y-intercept for those within walking distance and those not.
d) Cannot be determined
