Vang · Answer 1

Expected Value (EV) = 40

Standard Deviation = 20

Coefficient of Variation = 0.5

Explanation:

Outcomes ($ millions) Probability

Recession $10 0.3

Normal Economy $50 0.5

Strong economy $60 0.2

Expected value, μ = Outcome * probability

= ($10 * 0.3) + ($50 * 0.5) + ($60 * 0.2) = 3 + 25 + 12 = 40

∑ (x₁ - μ) ²

Standard deviation, σ = √ (∑ (x₁ - μ) ²) / N

X = Outcomes

μ = Expected value

X (x - μ) (x₁ - μ) ² (x₁ - μ) ²) * Probability

10 10 - 40 = - 30 900 900 * 0.3 = 270

50 50 - 40 = 10 100 100 * 0.5 = 50

60 60 - 40 = 20 400 400 * 0.2 = 80

Total = 400

Standard deviation = √400 = 20

Coefficient of Variation = Standard deviation / Mean

= 20 / 40

= 0.5
