(24 points total) 1. (12 points total) For each of the six coefficients (i.e., including the constant C), mark them with a single asterisk (*) if they are significant only at the 5% level (i.e., 0.01 < p-value < 0.05) and with a double asterisk if they are significant at the 1% level (i.e., p-value <0.01). Leave them blank if they are not significant at either 5% or 1%.
