(x,y) are bivariate gaussian. e(x)=10, e(y)=5, sd(x)=2 sd(y)=100, and the correlation coefficient is 0.99. Suppose you found that x=17. With this information, predict the z score of Y.

• z=0.9997, which is almost the same as the z score for x
• z=0.9997, which is a lot smaller than the z score for x
• x=0.0010, which is much smaller than the z score for x
• z=3.465, which is almost the same as the z score for x
• z=3.465, which is a lot smaller than the z score for x
