I think the correct answer would be the first option. Deadweight losses occur when the quantity of an output produced is less than, but not when it is greater than, the competitive equilibrium quantity. It is also known as allocative inefficiency. It is a loss of efficiency that will happen when the equilibrium of a good is not reached or the supply and the demand of a good are not in equilibrium such that the quantity of the goods is less than the equilibrium quantity. It is a loss due to inefficient use of the resources available. Price controls, minimum wage and taxation are said to cause deadweight loss.
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: A - Throughout the course of the trading day, an investor performs several cash transactions in his account which total $12,000.
