Answer:
lower range 33.822 years
upper range 38.178 years
Explanation:
step 1:
48 -1 = 47
step 2:
(1 - 95%) / 2 = 0.025
step 3:
we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117
step 4:
divide sample standard deviation by square root of sample size
7.5 years / √48 = 7.5 / 6.9282 = 1.0825
step 5:
multiply results from step 3 and 4
2.0117 x 1.0825 = 2.178
step 6:
for the lower range, subtract step 5 from sample mean
36 - 2.178 = 33.822
step 7: for the upper range, add step 5 with sample mean
36 + 2.178 = 38.178
Answer:
The BCWS is also known as Planned Value (PV).
So, in this way, <em>PV = 3.125.000</em>
Explanation:
With the data we can obtain the PV as follows:
First, let's calculate EV as EV = CV + AC.
EV = -500.000 + 4.000.000 = <em>3.500.000</em>
After this, we can calculate PV with this formula: SPI = EV/PV
PV = EV/SPI
PV = 3.500.000/1.12 = <em>3.125.000</em>

<em>We can conclude, with these results, that the project actually is forward about the schedule but with an overcost about the budget. In other words, the project advance must be 41% but now is on 36% due to the negative variance on the costs (CV).</em>

Answer:
The amount of deposit is 369.77 dollars
Explanation:
We can calculate the amount of deposit using present value and the number of payment periods, which is 17. It tells us about the value of our future income as measured in today's dollars. Future value for all four years is 1600 dollars. Formula for present value is future value/(1+interest rate)^number of periods. In this case it will be 1600/1.09^17 or 1600/4.327 equals 369.77.
Answer: a. benefits Boxlandian consumers by $672 and harms Boxlandian producers by $598.50.
Explanation:
Equilibrium price will be at level where quantity demanded equals quantity supplied.
200 − 2P = -60 + 3P
200+60 = 5P
5P = 260
P = $52
Equilibrium Quantity Demanded = 200 − 2P = 200 - 2 * 52 = 96 units
In a no-trade situation the demand in Boxland is 96 units at a price of $52. If they were to buy at the world price of $45, they would benefit;
= (96 * 52) - (96 * 45)
= 4,992 - 4,320
= $672
Producers however would produce the following at a price of $45;
Q S = -60 + 3P
= -60 + 3(45)
= 75 units
They would be supplying less units and be hurt.
