Let X denote the size of a bodily injury claim and Y denote the size of the corresponding property damage claim. Let Z1 = X + Y. From prior experience we know Var(X) = 144, Var(Y) = 64 and Var(X + Y) = 308. It is expected that bodily injury claims will rise 10% next year and property damage will rise by a fixed amount of 5. Let Z2 be the new trial of bodily injury and property damage. Compute...

] Let X denote the size of a surgical claim and let Y denote the size of the associated hospital claim. An analyst is using a model in which Var[X] = 2.4, E[Y ] = 7, E[Y^2 ] = 51.4 and Var[X + Y ] = 8. If a 20% increase is added to the hospital portion of the claim, find the variance of the new total combined claim

Two genes’ expression values follow a bivariate normal distribution. Let X and Y denote their expression values respectively. Also assume that X has mean 9 and variance 3; Y has mean 10 and variance 5; and the covariance between X and Y is 2. In a trial, 50 independent measurements of the expression values of the two genes are collected, and denoted as 1 1 ( , ) X Y , …, 50 50 ( , ) X Y ....
