WebFormula Margin of error = 1.96 x √ ( (N - n)/ (n-1)) x √ (p (1-p)/n) Solution : Margin of error = 1.96 x √ ( (8 - 6)/ (6-1)) x √ ( (0.8 x (1 - 0.8))/6) x 100 = 1.96 x √ (2/5) x √ ( (0.8 x (0.2))/6) x 100 = 1.96 x √ (0.4) x √ (0.16/6) x 100 = 1.96 x √ (0.4) x √ (0.0267) x 100 = 1.96 x 0.6325 x 0.1634 x 100 Margin of error = 17.1083 % WebDr C 9 years ago There are two possible explanations: The relevant variance is p (1-p), your calculation of √p (1-p) is the standard deviation. If that's not the reason, then note that Sal is working by treating "successes" as a 1 and "failures" a a 0, and then applying the typical variance formula - including division by n-1.
