Sample Mean Given Confidence Interval. A confidence interval for a population mean with a known population standard deviation is based on the conclusion of the central limit theorem that the sampling . Instead of a single number for the mean, a confidence interval gives you a .

A confidence interval for a population mean with a known standard deviation is based on the fact that the sample means . Since confidence interval is symmetrical about mean of sampling distribution of sample means, so we want 0.99/2=0.495 probability on both sides of mean. The means and their standard errors can be treated in a similar fashion.

The means and their standard errors can be treated in a similar fashion.

This video explains how to determine the error bound and sample mean given a confidence interval. Since confidence interval is symmetrical about mean of sampling distribution of sample means, so we want 0.99/2=0.495 probability on both sides of mean. A confidence interval for a population mean with a known standard deviation is based on the fact that the sample means . Subtract the error bound from the upper value of the confidence interval · or, average the upper and lower endpoints of the confidence interval.
