chutney mary london st jamesWebb10 jan. 2024 · You can use our normal distribution probability calculator to confirm that the value you used to construct the confidence intervals is correct. For example, if X = 1.96, then that X is the 97.5 percentile point of the standard normal distribution. (set mean = 0, standard deviation = 1, and X = 1.96. See that 97.5% of values are below the X.) chutney mary set menuWebb1 Answer. The formula for standard deviation is sqrt ( [sample size] [probability of success] (1- [probability of success])). To find the sample size from the mean and success rate, you divide the mean by the success rate. If mean=10 and success=0.2, you do 10/0.2 to get your sample size, or 50 in this case. dfs oval footstool
