Answer
(a) 17.2, 17.2, 17.3, 17.3 g: accurate and precise as all numbers are very close to the true value
(b) 16.9, 17.3, 17.5, 17.9 g: not precise as difference between the values is large.
(c) 16.9, 17.2, 17.9, 18.8 g: not precise as the difference is large. Also not accurate since far from the actual value.
(d) 17.8, 17.8, 17.9, 18.0 g: not accurate as it is greater than the true value. Also not precise since values vary a lot.
