The shape of the sampling distribution of t is.
A)typically normally distributed
B)positively skewed
C)determined by the degrees of freedom
D)identical to the distribution of z when the sample size is 30 or more

Question

Quizplus · Accepted Answer

The shape of the sampling distribution of t is determined by the degrees of freedom. As the degrees of freedom increase, the t distribution approaches a normal distribution. However, for small sample sizes (less than 30), the t distribution is more spread out and has heavier tails than a normal distribution. Therefore, neither A nor D are correct. B is not generally true and is not a defining characteristic of the t distribution.
