WebTo compute the probability that an observation is within two standard deviations of the mean (small differences due to rounding): Pr (μ − 2σ ≤ x ≤ μ + 2σ) = F (2) − F (−2) = 0.9772 − (1 − 0.9772) = 0.9545 or 95.45%. This is related to confidence interval as used in statistics: μ ± 2σ is approximately a 95%. fried rabbit malta https://holybasileatery.com
