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
I don't know what your interest rates are but 1.10(10% increasing) is more then 1.01(1% increasing). Does this help?

The correct answer is Neutral stance
Answer: The amount of gross margin Mazer would report if the company uses absorption costing is $1350.
Explanation:
Given that,
Mazer Manufacturing Company produced = 2,000 units of inventory
Units Sold = 1,800 units
Variable product cost = $4 per unit
Fixed manufacturing overhead cost = $2,500
Sales price of the products = $6 per unit
Fixed manufacturing cost per unit = 
= 
= $1.25 per unit
Unit Product cost under Absorption costing = Variable product cost + Fixed manufacturing cost per unit
= 4 + 1.25
= $5.25
∴ Gross margin under Absorption costing = Sales Revenue - Cost of goods sold
= Units sold × sales price - Units sold × Unit Product cost under Absorption costing
= 1800 × 6 - 1800 × 5.25
= 10800 - 9450
= $1350
