The confidence interval uses the sample to estimate the interval of probable values of the population; the parameters of the population. The relationship between the confidence level and the significance level for a hypothesis test is as follows: Confidence level = 1 - Significance level (alpha) For example, if your significance level is 0.05, the equivalent confidence level is 95%. Confidence intervals are encountered in everyday life, and allow us to make probabilistic statements such as: "Based on the sample of observations we conducted, we are 95% sure that the unknown mean lies .
