  • 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
