The correct formula for degrees of freedom in a chi-square distribution is k-1, not k-2. Therefore, statement D is false. The other statements are true. The chi-square distribution is determined by its degrees of freedom (statement A), and it is appropriate for independent trials (statement E). The variable of interest is broken into mutually exclusive categories (statement B), and the expected number in each category is determined by the null hypothesis (statement C).
