For a given two random varlables X and Y with joint probability distribution function f(z, y). X and Y are said to be statistically independent if and only if f(z, y) = g(x)h(y) for some values of X and Y. Select one: O True O False The loaves of rye bread distributed to local stores by a certain bakery have an average length of 30 centimeters and a standard deviation of 2 centimeters. Assuming that the lengths are normally distributed. what percentage of the loaves are between 29.3 and 33.5 centimeters in length? Select one: O 36.32 % O 59.67 % O 92.34 % O 95.99 % If X is a random variable with a = 2,5 and u= 8.2. then E(X) = Select one: O-64.740 O -60.990 O 73.490 O 69.740
