Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067
Answer:
10% is a high-profit margin
Explanation:
Since Justine is just starting her new business this might actually be a bad idea because 10% is a high-profit margin. In new business, you need to start off with very small profit margins in order to attract customers with low prices and grow a loyal customer base. Once the business begins to grow and sales start kicking up then you may begin increasing your profit margins.

Answer: $32.05
Explanation:
Beta = 0.7
Dividend = $1.25
Growth rate = 4%
Risk free rate = 3%
Market return = 10%
Since, Required return = risk free rate + beta × (market rate - risk free rate)
We will then slot in the values and.this will be:
= 3% + 0.7 × (10% - 3%)
= 3% + (0.7 × 7%)
= 3% + 4.9%
=7.9%
The price of the stock will then be:
= D1/(Required return-Growth rate)
=1.25 / (0.079 - 0.04)
= 1.25 / 0.039
= $32.05
