Confidence interval

• How to Test the Mean of an Exponential Distribution
  Test an exponential population mean with an exact chi-square statistic, and use the same pivot to construct a confidence interval for the mean.
• How to Determine Sample Size for a Normal Mean
  Calculate sample size for estimating a normal population mean from the confidence level, desired margin of error, and standard deviation.
• Continuity Correction vs. Confidence Interval: What’s the Difference?
  A continuity correction improves normal approximations to discrete probabilities; a confidence interval estimates an unknown parameter. Here is when each applies.
• How to Find a Confidence Interval for a Uniform Distribution
  For independent Uniform(0, θ) data, use the sample maximum to derive an exact confidence interval, with formulas and a worked 95% example.
