Sample mean and Sample covariance is an estimate of the population mean mu and population covariance. -81 -81. This formula can be used when you know and want to determine the sample size necessary to establish with a confidence of the mean value to within.
Finding probabilities with sample.
The FORMULA for the Confidence Interval CI for means is. Sample mean and Sample covariance is an estimate of the population mean mu and population covariance. The following video shows how to find the sample mean and highlights the difference between the mean of a sample and the mean of a population. Half the population is below this value.
