In Pepperland, occupational success (measured by salary) is inversely proportional to the quantitative trait, "BlueMeanie-ness".
shtirl [24]

Answer:

Please see below

Explanation:

First of all we need to examine and rank all BlueMeanie-ness scores from the Pepperlanders who took the test.

Ranked scores (from lowest to highest):  8.85; 10.80; 62.98; 88.07; 90.50.

Since the rationale is: occupational success is inversely proportional to the BlueMeani-ness score, it follows that the lower the score, the higher the occupational success, measured by salary. Therefore, the individuals with their scores on the low end will have a higher salary and the individuals with the higher scores will have a lower salary.

Conclusion: The individuals with scores 8.85 and 10.80 will likely have the higher wages.
