B) When sampling without replacement, the sample size cannot be greater than 10 percent of the population size. C) All expected counts should be greater than 5.

D) The distribution of the sample should be approximately normal.
E) During the sampling process, each individual chosen should be independent of the next
Answer
Answer: D) The distribution of the sample should be approximately normal.
Explanation: Chi-square tests do not require the sample distribution to be normal. Instead, they require the sample to meet other conditions like having expected counts greater than 5.
