The following are the masses (in kg) of members in a club: 59, 44, 53, 49, 57, 40, 48, and 50. Calculate the mean mass.
44 kg
50 kg
40 kg
53 kg
Explanation
Mean(\(\overline{x}\)) = \(\frac{\sum{x}}{n}\)
Mean(\(\overline{x}\)) = \(\frac{ 59 + 44 + 53 + 57 + 49 + 40 + 48 + 50}{8}\)
Mean(\(\overline{x}\)) = \(\frac{397}{8}\) ≈ 50 kg
