# 22: Interactively Observe the Effect of Changing the Confidence Level and the Sample Size


Interactively Observe the effect of changing the confidence level and sample size

Below you can see several confidence intervals randomly created with a given sample size, n, and confidence level, CL, from a standard normal distribution ($$\mu = 0$$ and $$\sigma = 1$$).  Use the slider to see what happens when the sample size and confidence level are changed.  Note the trade off between most containing the population mean and having a small width of the confidence interval.

n = 50

CL = 0.90
