of a statistic (mean, proportion, or standard deviation, etc.). There is always a risk ofsampling error associated with an estimate. Confidence intervals are useful forestablishing bounds for estimating, in particular, the mean or standard deviation, butalso regression coefficients, proportions, frequency rates, and differences betweenpopulations. Also, a 95% confidence interval indicates that for 19 out of 20 samplestakenfromthesamepopulation,theseintervalswillcontaintheparameterstudied,withama...
