WebThe mean and variance of 10 observations were calculated as 15 and 15 respectively by a student who took by mistake 25 instead of 15 for one observation. Then, the correct standard deviation is 2. Explanation: Given n = 10, `barx` = 15. σ 2 = 15 `barx = (sumx_i)/10` = 15. σ 2 = `(sumx_i^2)/10 - (barx)^2` = 15. ⇒ `sum^10x_i` = 150 WebThe sum of the deviation from the mean is always equal to _____. 0 Because the sum of the deviation from the mean always equals _____, the variance gets around the problem by …
