how to calculate sample mean from confidence interval. Assuming a normal distribution of the sample mean m the confidence interval is CI m tSE where t is the quantile of the t-distribution with n-1 degrees of freedom. To calculate a confidence interval around the mean of data that is not normally distributed.

The motivation for creating this confidence interval. Assuming a normal distribution of the sample mean m the confidence interval is CI m tSE where t is the quantile of the t-distribution with n-1 degrees of freedom. Find the Z value for the selected confidence interval.

Assuming a normal distribution of the sample mean m the confidence interval is CI m tSE where t is the quantile of the t-distribution with n-1 degrees of freedom. Maybe we had this sample with a mean of 835. In this section well discuss two commands that estimate the mean value of a variable for a population and give you a 95 confidence interval for that estimate. This tutorial explains the following.
