D) Determining whether a categorical variable has a significantly different distribution of proportions than the expected distribution
E) Determining the best shape for a set of data
Answer
Answer: D) Determining whether a categorical variable has a significantly different distribution of proportions than the expected distribution
Explanation: The chi-square goodness-of-fit test assesses whether the observed distribution differs from an expected distribution.
