My hypothesis is that the top 3 sets (A, B and C) predict both the size of the angles and the lengths of the line better than the middle 3 sets (D, E and F) and the bottom sets (G, H and I). I think this is correct because the top set is supposed to be smarter and I think they should be able to estimate closer to the correct amount. The are 185 pieces of data in the whole population. 77 are in the top sets. 70 are in the middle sets. 38 are in the bottom sets. Overall, there is too much data so I need to choose a sample. I need to make sure my sample size is appropriate. 10 will be too small and is not enough to represent my population and 100 will be too large. I will choose a sample size of 40 as that is not too small...
