Answer:
d. Matt's statement is positive while Jean's statement is normative
Explanation:
A positive statement can be defined as any statement that is typically based on empirical evidence and as such can be tested, proven and verified. Also, a positive statement can be amended or rejected based on evidences that are available.
On the other hand, a normative statement can be defined as any statement that can't be tested, proven or verified because it is judgmental and based on opinions.
In this scenario, Matt observes that "there is a high correlation between educational attainment and the level of income." Jean concurs and adds that "high school graduates should all proceed to college"
Hence, Matt's statement is positive because it is an observation based on empirical evidence while Jean's statement is normative because it's simply his opinion or a value judgment.
