This question is false. Only some metals and only some one metals are good conductors. For example, water is a non metal but it is still a pretty good conductor . While wood is not so well a conductor. I cannot think of a metal that is not a conductor right now but for example copper is a good conductor.
because there are 4 people in total including Mrs Cats you would add up 33 + 17 + 3 + 6 to get 59 then you would divide that by the amount of people there are in this case 4 to get 14.75.
