Convulsions a sudden, violent, irregular movement of a limb or of the body, caused by involuntary contraction of muscles Hyponatremia - causes? Hyponatremia is a condition that occurs when the level of sodium in your blood is abnormally low. Sodium is an electrolyte, and it helps regulate the amount of water that's in and around your cells. Red Cell Crenation A process resulting from osmosis in which red blood cells, in a hypertonic solution, undergo shrinkage and acquire a notched or scallop...

TRUE or FALSE? Suppose that X1, X2,... is a stationary stochastic process with covariance function Rk = Cov(X1, X1+k), for k=0,1,... Then the variance of the sample mean can be represented as Var(X) = 1/n[Ro + 2(1-k/n)Rk] -Correct Answer TRUE TRUE or FALSE? If f(x, y) = cxy for all 0 < x < 1 and 1 < y < 2, where c is whatever value makes this thing integrate to 1, then X and Y are independent random variables. -Correct Answer TRUE. (Because f(x, y) = a(x)b(y) factors nicely, and t...
