| Abstract: | In 2012,the national college students′mathematical contest in modeling A problem′s attachment 1 shows evaluation results of some wine in a year. Analyzed of the evaluation results of the two wine-tasting,researched whether there were significant differences and which group′s results more reliable with application of probability and mathematical statistical hypothesis testing,finally it is concluded that the second group′s results more credible evaluation of wine. |
