A distributor of personal computers has five locations in a city. In the year's first quarter, the sales in units were: Location
Observed Sales (units) North side 70 Pleasant Township 75 Southwick 70 I-90 50 Venice Avenue 35 Total 300 For a goodness-of-fit test that sales were the same for all locations, what is the critical value at the 0.01 level of risk
1 answer:
Answer:
It is observed that the value of test statistics (19.168) is greater than the critical value (13.277), thus the rejected hypothesis, H₀ at α = 0.01.
There is enough evidence to conclude or deduce that sales were the same for all locations
Explanation:
Solution
Given that:
Object: Test whether the sales were the same for all locations by applying 1% significance level.
The Null Hypothesis H₀ : Sales were the same for all locations
E₁ = 70 +75 +70+ 50 + 35/5 = 60
The Alternative Hypothesis Hₐ : Sales were not the same for all locations
Now,
The decision rule:
the Level of Significance be α = 0.01
Degrees of freedom is df= Number of categories -1
=5-1 = 4

Answer: b) lower in long-run equilibrium than in short-run equilibrium.
Explanation:
A self regulating economy will try to move to the long run Equilibrium.
From the graph attached you will notice that the Price Level at the point where the Long Run Curve intersects with the Aggregate Demand curve is lower than the point where the Short Run Supply curve intersects with the same Aggregate Supply.
This means that Prices in the long term at equilibrium will be less than prices in the short term at Equilibrium should the Economy be a self regulating type that will move towards a long term Equilibrium.
