6. Consider the linear population model with intercept:$y_t = \alpha + \beta x_t + \varepsilon_t$The variance structure is known as below: $E(\varepsilon_t^2) = \sigma^2 h_t^2,$Which regression may obtain efficiency $\hat{\beta}$ estimator? (A) Regress \( y_{t} \) on 1, \( x_{t} \) (B) Regress \( y_{t} / h_{t} \) on 1/ht ,xt/ht(C) Regress \( y_{t} / h_{t}^{2} \) on 1/h2t ,xt/h2t(D) Regress \( y_{t} \) on 1/ht ,xt/ht(E) Regress \( y_{t} / h_{t} \) on 1, \( x_{t} \)
5. Consider the linear model with intercept: $y_t = \alpha + \beta x_t + u_t$ If the $A = \sum_{i=1}^{n} (x_i - \bar{x})^2$ is positive definite and $E(u_i \mid x_i) = 0, \forall t = 1, 2, \dots, T$, which statement is true under sample size $T \to \infty$. (A) \( \hat{\beta} \) is consistent, but we cannot judge whether \( \hat{\beta} \) is efficiency (B) \( \hat{\beta} \) is unbiased and efficiency (C) \( \hat{\beta} \) is consistent and efficiency (D) \( \hat{\beta} \) is, but we cannot judge whether \( \hat{\beta} \) is efficiency (E) \( \hat{\beta} \) is unbiased and consistent.
4. Consider the simple regression $y_i = \alpha + \beta x_i + \varepsilon_i$And suppose population parameter $\beta = 2$ and least square estimator $\hat{\beta} = 2.3$. Now consider the regression $(x_i - y_i) = \alpha^* + \beta^* x_i + u_i.$What is the value of \( \hat{\beta} \)? (A) 1 (B)-1 (C)-1.3 (D)-0.3 (E) 0.3

33. Based on the information in the passage, which of the following can most reasonably be inferred about Zhou Yu's decision to wait for a specific wind pattern before launching his attack? (A) Zhou Yu possessed a superior understanding of local environmental conditions that Cao Cao's forces lacked. (B) Zhou Yu was uncertain whether fire attacks could be effective against Cao Cao's chained ships. (C) The allied forces at Red Cliffs needed additional time to build and prepare their fire ships. (D) Zhou Yu preferred to avoid direct naval confrontation with Cao Cao's larger fleet entirely.
34. According to the passage, what was the immediate problem that Cao Cao's decision to chain ships together was intended to solve? (A) The allied forces had been attacking isolated ships individually. (B) The Yangtze River's strong currents were causing ships to drift apart. (C) His northern troops suffered from seasickness during naval operations. (D) Cao Cao needed to create a floating platform to transfer troops to shore.
35. What is the primary function of Paragraph 5 in the passage's overall argument? (A) It contrasts the tactical approaches used by the Spanish and Chinese navies. (B) It provides technical details about how fire attacks were physically carried out. (C) It introduces new historical evidence about the use of fire attacks in ancient warfare.
