Three students have made multiple measurements of the solubility of sodium chloride (in g of NaCl per 100 g of water). Their results are summarized in the table below. The correct value for the solubility of sodium chloride is 35.9 g.
Nicole - first trial - 35.4g, second trial - 36.1g, 3rd trial - 35.7g
Matthew - first trial - 31.8g, second trial - 34.1g, 3rd trial - 41.5g
leonard - first trial - 39.2g, second trial - 39.3g, 3rd trial - 38.9g

a) Which student measurements have high precision but low accuracy?
b) Which student measurements are both accurate and precise?
