Question

a digital thermometer reports a temperature of 32.6°f as being 31.08°f. which of the following is true? a. the thermometer is accurate, but not precise. b. the thermometer is neither accurate nor precise. c. the thermometer is precise, but not accurate. d. the thermometer is both accurate and precise.

Explanation:

Accuracy refers to how close a measurement is to the true value. Precision refers to how close repeated measurements are to each other. Here, the true temperature is 32.6°F and the measured value is 31.08°F. There is a significant difference between the measured and true - value, so it's not accurate. Since no information about repeated measurements is given, but considering a single measurement is far from the true value, we can assume it's not precise either.

Answer:

B. The thermometer is neither accurate nor precise.
