Standard deviation in table
WebbFinal answer. Use the data in the table below to answer the following questions. a. Calculate the standard deviation (sigma). b. Identify the safety factor for a service level of 96% and calculate the safety stock. c. Calculate the order point if lead time is 5 days. Webb3 sep. 2024 · The standard deviation is the square root of the sum of the values in the third column. Thus, we would calculate it as: Standard deviation = √(.3785 + .0689 + .1059 + .2643 + .1301) = 0.9734 The variance is simply the standard deviation squared, so: Variance = .97342 = 0.9475
