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

(B) Body-composition improvements were more pronounced during the first four weeks than during the final four weeks of the intervention. (C) Heart-rate monitors and ratings of perceived exertion were used to verify that participants maintained the intended training intensity. (D) Blood samples were also analyzed for fasting glucose and insulin sensitivity, both of which improved significantly more.

50. Which of the following statements is NOT correct according to the passage? (A) Training sessions were scheduled three times per week on nonconsecutive days, and all sessions were conducted in the evening on a motorized treadmill. (B) To ensure a fair comparison, the two exercise protocols were executed so that participants in both groups expended a similar estimated amount of energy per session. (C) After completing the 8-week intervention, participants’ waist-to-hip ratios had dropped to the normal reference range established for Asian adults of their age group. (D) The researchers acknowledged that the absence of a non-exercise control group and the lack of rigorous dietary monitoring were notable limitations of the study
