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…

The correct answer is B. 7.6in (193mm). The mean is calculated by summing all values and dividing by the count. In inches: 5.6 + 11 + 3.6 + 13 + 4.4 = 37.6. Divided by 5 fish: 37.6 ÷ 5 = 7.52in ≈ 7.6in. In millimeters: 152 + 280 + 91 + 330 + 112 = 965mm. Divided by 5: 965 ÷ 5 = 193mm. The other options represent…

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?

Explanation

The mean is calculated by summing all values and dividing by the count. In inches: 5.6 + 11 + 3.6 + 13 + 4.4 = 37.6. Divided by 5 fish: 37.6 ÷ 5 = 7.52in ≈ 7.6in. In millimeters: 152 + 280 + 91 + 330 + 112 = 965mm. Divided by 5: 965 ÷ 5 = 193mm. The other options represent individual measurements (3.6in, 13in) or an incorrect calculation (6in/152mm).
