Suppose a study estimated the population mean for a variable of interest using a % confidence interval. If the width of the estimated 99%confidence interval (the difference between the upper limit and the lower limit) is and the sample size used in estimating the mean is , what is the population standard deviation? The population standard deviation is nothing.
