(a) (b) (C) (d) Consider a standard normally distributed variable, a tdistributed variable with (1 degrees of freedom, and an F-distributed variable with (1, (1) degrees of freedom. Which of the following statements is FALSE? The standard normal is a special case of the t-distribution, the square of which is a special case of the F -distribution. * Since the three distributions are related, the 5% critical values from each will be the same. Asymptotically, a given test conducted using any of the three distributions will lead to the same conclusion. The normal and t distributions are symmetric about zero while the F- takes only positive values
