Question
Let (X, : n > 1) be an infinite sequence of random variables. Consider the following
statements:
Statement A: If X, is normally distributed with mean 0 and variance rn, then for all
e > 0,
P(-e <
e) → 1
as n → 0.
Statement B: If X, has a x? distribution withn degrees of freedom, then X,
converges to some X in distribution as n → ∞, with P(X = 0) = 1.
Statement C: If X, has a t-distribution with n degrees of freedom, then X,
converges to some X in distribution as n → 0, with X having a continuous
distribution and satisfies P(X<1) = 0.48.
Which of the statements are true?
