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

複選題59.(AB) In practice, frequent changes in direction under successive presidential administrations have disrupted the continuity necessary for such ambitious undertakings. (AC) Commercial commitments, international commitments and now the government—all three working together is what’s really enabled humans to get to this point. (AD) The United States’ former rivalry with the Soviet Union has transitioned into a more complex competition involving a diverse array of nations with their own strategic lunar objectives. (AE) While Artemis II is a lunar flyby rather than a landing, it marks a significant milestone: the first crewed mission to the lunar vicinity since the Apollo program in 1972. (BC) Much of the industrial infrastructure and specialized expertise that supported the Apollo missions no longer exists, making a direct replication of 1960s technology impractical. (BD) The protracted interval between these landmark missions is fundamentally a byproduct of oscillating political will and shifting national priorities.   (BE) This shift requires the development of durable habitats and adaptable landing systems capable of operating in the lunar environment for extended periods.

62. In the realm of microbiology, bacteriophages, or phages, play a pivotal role in a specialized biomedical application known as phage therapy. Bacteriophages are viruses that infect and replicate within bacteria, and their unique ability to target specific bacterial strains makes them valuable tools for combating bacterial infections. Phage therapy involves utilizing these viruses to treat bacterial infections in a highly targeted manner, offering an alternative to traditional antibiotics. This specialized biomedical intervention has gained renewed interest as researchers explore personalized medicine, tailoring bacteriophages to individual patients based on the specific bacterial strains causing infections. The potential of phage therapy lies in its specificity and ability to evolve alongside bacteria, presenting a promising avenue in the ongoing battle against antibiotic-resistant pathogens. Which of the following statements best explains why doctors are increasingly interested in phage therapy? (A) Phage therapy is a valuable tool for combatting bacterial infections. (B) It is based in microbiology and makes use of bacteriophages. (C) It is the only way to combat illnesses caused by antibiotic-resistant pathogens. (D) Phage therapy can be personalized to address the needs of individual patients, making it a potential solution for unique or difficult-to-fight infections.
