Question

Suppose that the expected value of a measurement is 77 g. Which of the following sets of measurements is the MOST accurate?

A. 35 g, 80 g, 74 g, 56 g
B. 71 g, 75 g, 74 g, 74 g
C. 74 g, 76 g, 75 g, 75 g
D. 75 g, 77 g, 76 g, 76 g

Answer 1

Answer: D) 75 g, 77 g, 76 g, 76 g

Step-by-step explanation:

The most accurate set of measurement is the one that either has 77g as one of its subsets or has values that are closest to 77g.

So, by the already stated condition

- 35 g, 80 g, 74 g, 56 g is not accurate

- 71 g, 75 g, 74 g, 74 g is quite accurate

- 74 g, 76 g, 75 g, 75 g is quite accurate

- 75 g, 77 g, 76 g, 76 g is MOST ACCURATE

Thus, Option D with 75 g, 77 g, 76 g, 76 g is the most accurate set of measurement.
