We know from class that two random variables independent of each other are also uncorrelated. However, the opposite is not true in general: two uncorrelated random variables can be dependent. Consider a pair of random variables (X, Y ) with joint pmf given by y p(x, y) 0 1 −1 1 3 0 x 0 0 1 3 1 1 3 0 Show that X and Y are uncorrelated, but not independent. (Justify every step of computation.)

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
