Which of the following is TRUE about t distributions?
A)There are exactly 10 categories of t distributions.
B)For any given sample size, there are between two and N-1 appropriate t distributions.
C)The larger the sample size, the more a t distribution resembles a normal curve.
D)t distributions are generally bimodal.

Question

Quizplus · Accepted Answer

As the sample size increases, the t distribution approaches a normal distribution in shape. None of the other options are true. There is no fixed number of categories for t distributions (Option A). The appropriate t distribution depends on the specific conditions of the problem and cannot be generalized (Option B). t distributions are not bimodal; they are unimodal (Option D).
