As the Number of Degrees of Freedom for a T-Distribution

Short Answer

As the number of degrees of freedom for a t-distribution increases: $\begin{array}{|l|l|}\hline A&\text {the dispersion of the distribution decreases. }\\\hline B&\text {the shape of the distribution becomes narrower and taller. }\\\hline C&\text { the \( t \)-distribution becomes more and more similar to the standard normal distribution.}\\\hline D&\text {All of these choices are correct. }\\\hline \end{array}$
