Question
**6.4.2.** Let \( X_1, X_2, \ldots, X_n \) and \( Y_1, Y_2, \ldots, Y_m \) be independent random samples from \( N(\theta_1, \theta_3) \) and \( N(\theta_2, \theta_4) \) distributions, respectively. (a) If \( \Omega \subset R^3 \) is defined by \[ \Omega = \{ (\theta_1, \theta_2, \theta_3) : -\infty < \theta_i < \infty, \, i = 1, 2; \, 0 < \theta_3 = \theta_4 < \infty \}, \] find the MLEs of \( \theta_1, \theta_2, \) and \( \theta_3 \). (b) If \( \Omega \subset R^2 \) is defined by \[ \Omega = \{ (\theta_1, \theta_3) : -\infty < \theta_1 = \theta_2 < \infty; \, 0 < \theta_3 = \theta_4 < \infty \}, \] find the MLEs of \( \theta_1 \) and \( \theta_3 \).
