The confidence level of an interval estimate of a parameter is the
... • A point estimate is a single value. The problem with point estimates is that the accuracy of the estimate cannot be determined, so the interval estimate is preferred. • By calculating a 95% or 99% confidence interval about the sample value, statisticians can be 95% or 99% confident that their esti ...

That is, if you always employ a significance level of .05, then 5% of those times when the null actually is true, you will incorrectly reject it. Incorre ...
