Question

A student measured the length of a piece of twine that was 35.84 mm long. Her measurements were 37.52 mm, 37.54 mm, 37.57 mm and 37.55 mm. Which of the following statements is true?A. The measurements were accurate but not precise. B The measurements were precise but not accurate. C.The measurements were both precise and accurate. D.The measurements were neither accurate nor precise.

Answer 1

Answer:

Option B, The measurements were precise but not accurate.

Explanation:

Precision is the nearness in two or more measurements taken at a time.  

Here the measurements 37.52 mm, 37.54 mm, 37.57 mm and 37.55 mm are very close to each other. Hence they are precise

But since none to these measurements are close to the standard value 35.84 mm hence they are not accurate.  

Therefore, the measurements are precise but not accurate.

Option B is correct.
