Like that of the Student t-distribution, the shape of the chi-squared distribution depends on:

A) the population size
B) the number of its degrees of freedom
C) the population standard deviation
D) whether the population is unimodal or bimodal
E) none of these

The shape of the chi-squared distribution depends on the number of its degrees of freedom. The distribution is skewed to the right and becomes more symmetrical as the degrees of freedom increase. The population size, population standard deviation, and whether the population is unimodal or bimodal are not factors that affect the shape of the chi-squared distribution.
