2.自世界衛生組織於2020年3月宣布新冠肺炎造成全球大流行以來,疫 情對民眾日常生活和全球社會經濟的影響與日俱增。面對此次疫情,我 國農政機關陸續推動農業相關防疫、紓困和振興措施,確保農產品供應 無度,並減低農部門所受衝擊。為了瞭解「農業旅遊人數減少是否影 響全臺休閒農場的經營發展」,請設計一個抽樣調查,具體說明抽樣規 制與抽樣原理,使得此研究的調查結果能合理推論臺灣的狀況並回答此 問題.(本題20分)

3.假設您有機會取得財政單位一整年度的超商電子發票資料,請嘗試以城 鄉食品消費差異為例,撰寫一份量化研究的研究計畫構想書,內容包 括:研究問題、研究目的、分析架構、列舉兩個研究假設、以及如何使 用統計方法進行分析。(本共25分)

(1)此分析的假設檢定是什麼?(3分)

(2)a=0.05顯著水準是什麼意思?(3分)

(3)根據居民主觀感知的結果,A村與B村的農地買賣現象有沒有差異? 請說明統計發現.(4分)

(1)任何統計分析方法皆有其前提假設,請問多元迴歸分析的前提假設包含哪些條件?(10分)

(2)根據統計分析結果,影響獲得農村再生計畫補助件數的可能因子有 哪些?請說明統計發現。(10分)

(a) (5 points) Let us introduce the slack variables x3, x4, x5, x6 to constraints 1, 2, 3, and 4, respectively so X1,1220 that the objective function and equations, which are called dictionary, can be written asWe let x3,x4,x5,X6 in the above dictionary be basic variables, and x1and x2 be the nonbasic variables. What is the initial feasible solution (x1, X2,X3,X4.X5, X6.Z) based on the above dictionary in (a) if both nonbasic variables are set as zero?

(b) (5 points) There are totally six variables, x1, x2,X3,X4, X5,X6, with only four equations. Four out of six variabies can be expressed by the remaining two variables. For example, x3 is cxpressed by x1 and X2. Similarly, x4, x5, x6 arc expressed by X1 and x2 as well. Since we would like to increase z, let us increase x, from zero. To kecp the feasibility, what is the maximum value we are able to increase the value in x1?

(c) (5 points) In (a), the current basis is composed of x3,x4,X5, X6. Suppose x1 enters the basis and x3 lcaves the basis. What is the dictionary at the next iteration? In other words, please complete the followings.
