8. If you measure the density of a metal block 3 times and obtain values of 34.4 g/ml, 34.3 g/ml, and 34.4 g/ml for the three trials you can probably assume that you have [ GOOD / POOR] [ACCURACY / PRECISION].

9. If you compare the three masses obtained for the metal block in the previous problem with the value of 3.25 g/ml obtained from a literature source for that particular metal, you can probably assume that you have[ GOOD / POOR] [ACCURACY / PRECISION].
