Transcribed Image Text:**Problem 7: Bivariate Normal Distribution**
Given that the random variables \( X \) and \( Y \) have a bivariate normal distribution with the following parameters:
- Mean of \( X \) (\( \mu_1 \)) = 3.2
- Mean of \( Y \) (\( \mu_2 \)) = 1.44
- Standard deviation of \( X \) (\( \sigma_1 \)) = 12
- Standard deviation of \( Y \) (\( \sigma_2 \)) = 16
- Correlation (\( \rho \)) = 0.7
**Determine the following quantities:**
(a) \( E(X) \), \( E(Y) \), \( Var(X) \), \( Var(Y) \), \( \rho(X,Y) \), and \( Cov(X,Y) \).
(b) The distribution of \( X \) and the distribution of \( Y \).
(c) The probabilities \( P(0.8 < X < 4.2) \) and \( P(Y > 14) \).
(d) The conditional distribution of \( Y \), given \( X = 3.8 \).
(e) The conditional distribution of \( X \), given \( X = 10 \).
(f) The probabilities \( P(X > 3.2|Y = 10) \) and \( P(Y < 12|X = 3.8) \).
(g) \( E(X|Y = 10) \), \( E(Y|X = 3.8) \), \( Var(X|Y = 10) \), \( Var(Y|X = 3.8) \).
