tail. The lower bound of the 95% confidence band for R is called R_MIN: R_MIN = μΔt − 1.96σ√Δt = 0.001923 − 1.96 × 0.027735 = −0.0524 The upper bound of the 95% confidence band for R is called R_MAX: R_MAX = μΔt + 1.96σ√Δt = 0.001923 + 1.96 × 0.027735 = 0.0563. This gives S_MIN = $100exp(−0.0524) =
