   What is a confidence interval?

   • Level of confidence: This is the probability that the confidence interval contains the true population parameter. The most commonly used level of confidence is 95%, which means that if we were to take many samples and calculate a confidence interval for each one, approximately 95% of those intervals would contain the true parameter value.
