Explanation:

Question #8

Descriptive statistics summarizes or describes data (like odds here, a direct description of lottery winning chance). Inferential stats makes inferences/predictions. The lottery odds are a direct description, so it's descriptive.

The claim about a relationship between smoking and COVID - 19 infection is an inference (drawing a conclusion about a relationship, likely from analyzing data to infer a pattern), so it's inferential statistics. Descriptive stats just describes data, not infers relationships.

Answer:

A. Descriptive statistics
