c(ii) sub into estimated equation, if not given value of income, maybe use the mean value
c(iii) do an f-test for joint significance.

Thanks truetears- i found the answers to this- can I ask: (b) asked what is the relationship of income and child's height (I said linear because income^2 has. Coefficient of 0- but the answers still said it was parabolic... Why is this the case?)

lol doesn't really matter, ye it's pretty much linear since the coefficient is almost 0. The answers are just being pedentic, even though output says 0.0000, its actually not exactly 0... and since its statistically significant (but not really economically significant), the coefficient still exists, hence parabolic relationship
