Answer:
option d) approximately 84%
Explanation:
Data provided in the question:
Mean, m = $92
Standard deviation, s = $13
Now,
we have to calculate percentage of homes will have a monthly utility bill of more than $79 i.e P(X > 79)
also,
P( X > 79) = 1 - P( X < 79)
Z-score for (X = 79 ) =
Z =
or
Z = -1
From the standard Z value vs P table, we have
P( Z < -1 ) = 0.1587
Thus,
P( X < 79) = P( Z < -1 ) = 0.1587
therefore,
P(X > 79) = 1 - 0.1587
or
P(X > 79) = 0.8413
or
= 0.8413 × 100%
= 84.13%
Hence,
option d) approximately 84%
Answer:
c. fall in the short run, and fall even more in the long run.
Explanation:
The aggregate demand shifts to the left in recession or contractions, in consequence the level of prices falls. For this analysis we consider the shor-run supply curve with a positive slop.
As we know, the economy in the long run tends to equilibrium, where the the production level is fixed and equal to the potential of production of the economy. The initial reduction of prices incentives the consumption in the long run, stabilizing with the long run quantites in a minor level of prices.
