Question

The mass of an object was measured eight times on a balance readable to $pm$1 g, and the following values were recorded: (298 $pm$ 1)g, (311 $pm$ 1)g, (302 $pm$ 1)g, (312 $pm$ 1)g, (313 $pm$ 1)g, (317 $pm$ 1)g, (302 $pm$ 1)g, and (331 $pm$ 1)g. Find the standard error of mean $sigma_m = frac{s_m}{sqrt{N}} = sqrt{frac{1}{N(N-1)}sum_{i=1}^{N} (ar{m} - m_i)^2}$ Select one: a. 3.71 b. 5.57 c. 2.97 d. 4.45
