This calculator will compute the 99 95 and 90 confidence intervals for the mean of a normal population when the population standard deviation is known given the sample mean. A confidence interval of 95 signifies that in a sample or population analysis 95 of the true values would provide the same mean valueeven if the statistical test is repeated multiple times.

Sample 1 mean sample 2 mean. When you put the confidence level and the confidence interval together you can say that you are 95 sure that the true percentage of the population is between 43 and 51. This confidence interval calculator reports the results in APA style.

So for example if the confidence level is 95 the confidence coefficient is 95.
