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:
1. Actual Price
2. Misperceptions theory.
Explanation:
In the short run, the quantity of output that firms supply can deviate from the natural level of output if the ACTUAL PRICE level in the economy deviates from the expected price level. Several theories explain how this might happen.
For example, the MISPERCEPTIONS THEORY asserts that output prices adjust more quickly to changes in the price level than wages do, in part because of long-term wage contracts. Suppose a firm signs a contract agreeing to pay its workers $15 per hour for the next year, based on an expected price level of 100 Year.
The above explanations is the reason why the aggregate supply curve slopes upward in the short run
Answer:
The broker is doing two different jobs; so it is okay to have two different licenses.
Explanation:
In this case, since the broker is doing two different jobs then it is okay for him to have two different licenses. In a hypothetical case that the individual Broker was doing the same job role for two different companies then that would be considered a form of conflict of interest and may cause problems with both firms in the future. Since this is not the case, then he should not have any problem.

Answer:
4%
Explanation:
If the real gross domestic product for the year grew by 2%
The inflation rate also grew by 2%
Then nominal GDP rate can be calculated as follows
= Real GDP + inflation rate
= 2% + 2%
= 4%
Hence the nominal gross domestic product grew by 4%
