WebMay 8, 2024 · To solve for sample standard deviation s, we use the mathematical definition for a margin of error for ˆμ, which is M E = zα/2 ⋅ s √n provided the sample size is large enough (usually at least 30 or 40). Solving this for s gives s = M E ⋅ √n zα/2 For a 95% C.I., we have α = 0.05, and zα/2 = 1.96 (from z -table lookup).
