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...

Predictive analytics in business is an important application of multiple regression analysis.Generallyspeaking,whatismeantbypredictiveanalytics?Asabusinessowner,howcouldyouuseregressionanalysisand predictive analyticsto increase your company'ssales?

Consider when businesses might use confidence intervals to estimate values, such asin sales projections, marketing results, and so forth. Describe a business decision thatcould be helped with confidence intervals. Be specific! Then create a problem withnumbers from which another student could calculate a confidence interval and make adecision.
