The F distribution takes non-negative values, so all values of X, which has an F distribution, are non-negative. Option A is incorrect because the F distribution is not necessarily symmetrical. Option C is incorrect because the mean of an F distribution depends on its parameters and is not necessarily zero. Therefore, option D is incorrect.
