A refrigerator thermometer is read ten times and registers degrees Celsius as: 39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1, 39.1, 39.4, and 39.1. However, the real
temperature inside the refrigerator is 37 degrees C. Is this an example of
precision, accurate, neither, both or neither, Make a selection and explain.

Precise, but not accurate

Explanation:

First, let’s define accuracy and precision.

Accuracy: how close you are to the actual value

Precision: how close the measurements are to each other.

Let’s examine the data given:

39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1, 39.1, 39.4, 39.1

Each number is very close to 39, within 0.1 to 0.4.

The actual temperature of the refrigerator is 37 degrees. Each measurement is about 2 away from 37.

Since the measurements are close to each other, but far from the true value, we can say this is precise but not accurate.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
