Which of the following statements is true with respect to the t distribution?

A) The t distribution is more spread out than the standard normal distribution.
B) The t distribution is symmetrical.
C) The shape of the t distribution depends on the number of degrees of freedom.
D) All of these.
E) None of these.

T Distribution

This type of probability distribution comes into play when attempting to estimate the mean of a normally distributed population, specifically when dealing with a small sample size and lacking knowledge of the population's standard deviation.

Degrees Of Freedom

The number of values in a calculation that are free to vary, often related to the sample size, affecting the shape of various statistical distributions.

Standard Normal Distribution

A normal distribution with a mean of zero and a standard deviation of one, used as a basis for comparison in many statistical methodologies.
