The calculated value of the Z statistic to test the potential buyer's belief at the 1% significant level is -2.57512627.
The calculated Z score is slightly greater than the critical value of -2.575, the potential buyer's view that weekly store revenues are less than $7,000 stands vindicated.
Since store revenues are assumed to be normally distributed and population standard deviation is given, we can use the Z-test. The relevant test statistic is the Z-score.
We use the following formula for calculating the Z score:
Z = (X - μ) / (σ /√n)
Substituting the relevant values we get,
Z = (6400 -7000) / (1042/√20)
Z = -600 / 232.9982833
Z = -2.57512627
Answer:
Quantity of oil bought & sold would depend upon relative change i.e increase & decrease in demand & supply respectively.
- ↑Dd = ↓Sy : Qty same
- ↑Dd > ↓Sy : Qty ↑
- ↑Dd < ↓Sy : Qty ↓
Explanation:
Libya is an exporter of Oil to China. It implies china's demand for oil is satisfied by Libya's imports.
Usual markets are at equilibrium when market demand = market supply, demand & supply curves intersect.
Political unrest in Libya decreasing oil production, would decrease supply (exported) of oil to China & sift supply curve leftwards. Simultaneously, increase in China demand for oil would shift the demand curve rightwards. These changes in demand, supply would create excess demand. Excess demand would cause competition among buyers & increase the new equilibrium price.
However, <u>Quantity </u>of oil bought & sold would depend upon relative change , shift in demand & supply. If increase in demand is equal to decrease in supply, the quantity would remain<u> same.</u> If increase in demand is more than decrease in supply, quantity will <u>increase</u>. If increase in demand is less than decrease in supply, the quantity will <u>decrease.</u>
Answer:
price per unit times the number of units sold.
Explanation:
total revenue = total number of units sold x price per unit
the other options are incorrect because:
- the variable cost per unit times the number of units sold = total variable costs
- the change in revenue when one additional worker is hired = marginal revenue product of the additional worker
- firms seek to maximize profits, not revenue
Answer:
Correct option is C
Explanation:
Increase in \alpha decreases πt - π(t-1) which shows decrease in natural rate of unemployment.
Phillips bend clarifies the connection between expansion rate and joblessness rate. As indicated by it there is a reverse connection between the joblessness rate and swelling rate. It implies there is an exchange off among expansion and joblessness rate.
The strategy ramifications of Phillips bend is that administration can't lessen swelling and joblessness together. It joblessness decreases, at that point the economy must acknowledge higher expansion. Then again, on the off chance that economy lessens expansion, at that point it must acknowledge higher joblessness.
When there is synchronous change in the swelling rate and joblessness rate then this is an instance of development along the short-run Phillips bend.
Then again, when either joblessness rate or swelling rate stays unaltered while different changes then it prompts moving of short-run Phillips bend.
