比率 P 得假设检验及其应用比率 P 得假设检验及其应用摘要:假设检验就是统计推断得另一项重要内容,它与参数估量类似,但角度不同。参数估量就是利用样本信息推断未知得总体参数,而假设检验则就是先对总体参数提出一个假设值,然后利用样本信息推断这一假设就是否成立。本文将主要介绍总体比率得假设检验得原理与方法,以及其在各种生活实例中得应用,从而更深得了解假设检验在各种统计方法中得重要作用.关键词:假设检验;总体比率;检验统计量;拒绝域Hypothesis T esting and I ts A p plicat i o n of Ra t io PAb s t rac t:Hypothe si s testing i s anoth er important content to s tat is t ic al i n f e re n c e, and it i s sim i lar to parameter e stim a tion, but the Ang l e is differ en t、 Pa r ameter estimati o n is use sa m p le informa t i o n to in fe r a n u n known pop ul atio n p ara m e te r, and the hypothesi s testing i s a hy p othesis is p r opose d fi r st in th e o ver a ll p arame t ers, and t h en using t h e s amp l e i n f orma t ion t o determi n e w heth e r t h e hypothes i s i s e s tab l ished、 Th is arti c l e ma inl y introduces the overall rate of t he p rinciple a nd m etho d o f hypo thesi s testing, an d it s appl i cation in all kinds of livi n g examples, t h u s deep e r unders tan di n g of the hy p othe s is testing pla ys an im portant part in all k i n ds of s tatis t ic al method s、Key wor d s:hy po t hesi s testing;the ov e rall ra t e;te s t statistic s;reject i on r e g i on目录一、假设检验得基本问题 (一)假设检验得概述 (二)假设检验得基本步骤 (三)检验得 P 值二、总体比率得假设检验及其应用 (一)单个总体比率得假设检验 1...
