Explanation:

First Question (Descriptive Statistic)

Descriptive statistics summarize sample data. Option A is just the sample size. Option B describes the proportion (64%) of the sample (surveyed women) as primary investors, which is descriptive. Option C is incorrect (no association claim here). Option D is an inference (about the population), not descriptive.

Inference uses sample data to make claims about the population. Option A is descriptive (sample). Option B is incorrect (no association shown). Option C is sample size (descriptive). Option D infers that about 64% of all US women are primary investors, using the sample result.

Answer:

B. 64% of women in the sample are the primary investor in their household.
