Choose the letter of the correct answer. 1) Three students weigh a standard mass of 3.00 g on the same balance. Each students obtains a reading of exactly 1.85 g for the mass of the standard. What do these results imply? a) The balance used is accurate but nit precise b) The balance used is precise but not accurate c) The balance used is both accurate and precise d) The balance used is neither accurate nor precise 2) Aria and Jessi determined the mass of an object on two different balances. The accepted mass of the object was 2.355 g. Vivz obtained the following values: 2.531 g, 2.537 g, 2.535 g, and 2.533 g. Kenny obtained the values of 2.350 g, 2.404 g, 2.296 g, and 2.370 g. Which statement best describes the results that were obtained by Vivz and Kenny? a) Aria obtained the better precision. b) Aria obtained the better accuracy. c) Jessi obtained the better accuracy. d) Jessi obtained the better precision.
