The choline is then available for reuptake into the nerve terminal. These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。取顯著性水平 ?=，檢驗(yàn)該雜志讀者群中女性的比例是否為 80%？ H0 ： ? = 80% H1 ： ? ? 80% ? = n = 100 檢驗(yàn)統(tǒng)計量 : 1 0 0)( ??????z 結(jié)論 : 沒有證據(jù)表明 “該雜志聲稱讀者 群中有 80%為女性 ”的看法正確 有四個品牌的彩電在五個地區(qū)銷售，為分析彩電的品牌 (因素 A)和銷售地區(qū) (因素 B)對銷售量是否有影響，對每個品牌在各地區(qū)的銷售量取得以下數(shù)據(jù)，見下表。用 P 值進(jìn)行檢驗(yàn)比根據(jù)統(tǒng)計量檢驗(yàn)提供更多的信息．統(tǒng)計量檢驗(yàn)是我們事先給出的一個顯著性水平，以此為標(biāo)準(zhǔn)進(jìn)行決 策，無法知道實(shí)際的顯著性水平究竟是多少． 四、計算分析題： １０＋ 15=２５分 一種以休閑和娛樂為主題的雜志，聲稱其讀者群中有 80%為女性。因而從分析層次上講，回歸分析更深刻一些。與此同時，相關(guān)關(guān)系往往要通過回歸分析才能闡釋清楚，例如皮爾遜相關(guān)系數(shù)的 PRE 性質(zhì)。相關(guān)程度越高，回歸預(yù)測越準(zhǔn)確。 簡述回歸分析和相關(guān)分析之間的密切聯(lián)系。 同分對 如果在 X 序列中，我們觀察到 ijX=X （此時 Y 序列中無 ijY=Y ），則這個配對僅是 X 方向而非 Y 方向的同分對；如果
