WebHow to find a critical value for any confidence level (i.e. 90%, 95% etc.) in easy steps! WebTo calculate the upper and lower limits of the interval, take the positive critical value and multiply it by the standard error of the mean. Then take the sample mean and add and subtract that product from it. Lower Limit = Sample Mean – (CV * Standard Error of the Mean) Upper Limit = Sample Mean + (CV * Standard Error of the Mean)
