a) ( 0.8509718, 0.8890282)

b) ( 0.7255, 0.7745)

Explanation:

(a)

Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)

So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)

=0.01902816

So 95 % confidence interval is

p+/-E  

0.87+/-0.01902816  

( 0.8509718, 0.8890282)

(b)

Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245

So 95% confidence interval is

p+/-E

0.75+/-0.0245

( 0.7255, 0.7745)

Two investment opportunities are as follows:________. Alt A Alt B First Cost 200 100 Uniform annual benefit 32 27 End of useful
Talja [164]

Answer:

Since the 4.34 NPV of Alt A is greater than the 2.35 NPV of Alt B, it therefore implies that Alt A should be selected.

Explanation:

Note: The data in the question are merged together. They are therefore sorted before answering the question as follows:

                                                          Alt A              Alt B

First Cost                                           200                 100

Uniform annual benefit                       32                   27

End of useful life salvage value         20                    0

Useful life, in years                              10                     5

The explanation to the answer is now given as follows:

a. Calculation of NPV of Alt A

First Cost = 200

PV of uniform annual benefit = P * ((1 - (1 / (1 + r))^n) / r) ……………………. (2)

Where;

P = uniform annual benefit = 32

r = MACC = 10%, or 0.10

n = number of useful years = 10

Note: The formula for calculating the present value of ordinary annuity is being used here to calculate the Present Value (PV) of uniform annual benefit.

Substitute the values into equation (1) to have:

PV of uniform annual benefit = 32 * ((1 - (1 / (1 + 0.10))^10) / 0.10) = 32 * 6.14456710570468 = 196.63

PV of Salvage value = FV / (1 + r)^n ..................... (2)

Where;

FV = End of useful life salvage value = 20

r = MACC = 10%, or 0.10

n = number of useful years = 10

Note: The normal formula for calculating the present value (PV) is being used here to calculate the PV of Salvage value

Substitute the values into equation (2) to have:

PV of Salvage value = 20 / (1 + 0.10)^10 = 20 / 2.5937424601 = 7.71

Net present value (NPV) of Alt .A = PV of uniform annual benefit + PV of Salvage value - First cost = 196.63 + 7.71 - 200 = 4.34

b. Calculation of NPV of Alt B

First Cost = 100

PV of uniform annual benefit = P * ((1 - (1 / (1 + r))^n) / r) ……………………. (3)

Where;

P = uniform annual benefit = 27

r = MACC = 10%, or 0.10

n = number of useful years = 5

Note: The formula for calculating the present value of ordinary annuity is also being used here to calculate the Present Value (PV) of uniform annual benefit.

Substitute the values into equation (3) to have:

PV of uniform annual benefit = 27 * ((1 - (1 / (1 + 0.10))^5) / 0.10) = 27 * 3.79078676940845 = 102.35

NPV of Alt B = PV of uniform annual benefit - First cost = 102.35 – 100 = 2.35

c. Decision

Since the 4.34 NPV of Alt A is greater than the 2.35 NPV of Alt B, it therefore implies that Alt A should be selected.

The US agricultural sector experienced a severe drought in 2012. A drought decreases the supply of agricultural products, which
Nataliya [291]

Answer:

True

Explanation:

Exceptionally good weather will guarantee a good yield in crops. This will lead to an increase in supply of produce to the market, and when supply increases, the supply curve shifts to the right.

This is simply because there are more products and more sellers, and this will result in more supply.
