CompTIA Data+ (DA0-001) — Question 359

A biologist is recording the length of five fish with the following measurements:

5.6in (152mm)
11in (280mm)
3.6in (91mm)
13in (330mm)
4.4in (112mm)

Which of the following is the mean length of the five fish?

Answer options

Correct answer: B

Explanation

To calculate the mean length, add all the lengths together: 5.6 + 11 + 3.6 + 13 + 4.4 = 39.6 inches. Then divide by the number of fish, which is 5, resulting in an average of 7.6 inches. The other options do not reflect this average calculation and are therefore incorrect.
