  • 8.1: A Single Population Mean using the Normal Distribution
    https://stats.libretexts.org/Courses/Penn_State_University_Greater_Allegheny/STAT_200%3A_Introductory_Statistics_(OpenStax)_GAYDOS/08%3A_Confidence_Intervals/8.01%3A_A_Single_Population_Mean_using_the_Normal_Distribution
    A confidence interval for a population mean with a known standard deviation is based on the fact that the sample means follow an approximately normal distribution.

Clearly, if you already knew the population mean, there would be no need for a confidence interval. However, to explain how confidence intervals are constructed, we are going to work backwards and begin by assuming characteristics of the population. Then we will show how sample data can be used to construct a confidence interval.
