Problem 3E

Write the bivariate normal pdf $$f\left(x, y ; \theta_{1}, \theta_{2^{\prime}}, \theta_{3^{\prime}} \theta_{4}, \theta_{5}\right)$$ in exponential form and show that $$Z_{1}=\sum_{i=1}^{n} X_{i}^{2}, Z_{2}=\sum_{i=1}^{n} Y_{i}^{2}, \quad Z_{3}=\sum_{i=1}^{n} X_{i} Y_{i^{\prime}} \quad Z_{4}=\sum_{i=1}^{n} X_{i}$$, and $$Z_{5}=\sum_{i=1}^{n} Y_{i}$$ are joint sufficient statistics for$$\theta_{1}, \theta_{2^{\prime}} \theta_{3} \theta_{4}$$, and $$\theta_{5}$$
