Highest selection rate: 50% (Whites)

Now apply the 4/5ths Rule:

80% × 50% = 40%

Minimum acceptable selection rate = 40%.

Now compare:

African Americans: 37.5% (below 40%) → Possible adverse impact

Hispanics: 20% ❌ (way below 40%) → Definite adverse impact

Whites: 50% → No issue.

Adverse impact is against Hispanics (not African Americans, not Whites, not Females).
