Suppose that X is uniformly distributed between 0 and 1. Given X = x, Y is uniformly distributed between 0 and x2. (a) Determine E(Y |X = x) and then Var(Y |X = x). Is E(Y |X = x) a linear function of x? (b) Find f(x, y) using fX(x) and fY |X(y|x). (c) Find fY (y). (d) Find the conditional density of X given Y = y. (e) Find the correlation coefficient between X and Y .
Assume that x is a uniformly distributed random number between 0 and 1 (e.g. x is the RAND() function in Excel), and that the number of units to be sold is uniformly distributed between 100 and 400. In this case, sales are given by the expression: 400 - 100 * x 100 + 400 * x 400 + x 300 + / - x
3. Suppose X is equally likely to be 0 or 2. (a) What is the mean of X? (b) What is the variance of X? (c) What is Pr{X-2| X 2)?

What is the difference between P(A|B) and P(A|B=x)? What is the difference between RVs and events?
What is the main difference between Classicals and Keynesians when it comes to their views of the role of government within a market system? Does the Classical view call for zero government? (Yes or No.) Is the Keynesian view a socialist or communist view? (Yes or No.) Does the goal of a fair distribution of income or wealth mean that incomes should be distributed equally? Explain.
What is the difference between replication and (two primary methods of) partitioning when dealing with distributed databases, and when would you use one partitioning method versus the other?
