Calculating Approximate Standard Errors and Confidence ...

The true population value is unknown, but there is an approximate 90% probability that the interval includes or “covers” the true population value. A 95% confidence interval is the range from 1.96 standard errors below the estimate to 1.96 standard errors above the estimate.

Standard Error and Confidence Intervals
academic.csuohio.eduaverage daily listening of “37 minutes, plus-or-minus 4.5 minutes at the 95% confidence level,” we would say that we are 95% certain that the true population mean (µ) is between 32.5 and 41.5 minutes. Although we may establish a confidence interval at any level (70%, 92%, etc.), three levels are commonly used:
