Study Notes
- To find the arithmetic means of given distributions.
- Given: CV₁ = 60, σ₁ = 25 and CV₂ = 70, σ₂ = 16
- The coefficient of variation formula is CV = (σ/μ) × 100, where μ ≠ 0.
- CV₁ = (σ₁/μ₁) × 100
- 60 = (25/μ₁) × 100
- μ₁ = 41.66
- CV₂ = (σ₂/μ₂) × 100
- 70 = (16/μ₂) × 100
- μ₂ = 22.87
- The value of μ₁ = 41.66 and μ₂ = 22.87.
