7 0

Answer:

± 4.05

Explanation:

Data provided in the question:

Random sample size = 15

Standard deviation = 8

Confidence level = 95%

Now,

Margin of error is given as:

Margin of error = ± [ ( z × s ) ÷ √n ]

Here,

From standard z table for 95% confidence level z = 1.96

Margin of error = ± [ ( 1.96 × 8 ) ÷ √15 ]

or

Margin of error = ± [ 15.68 ÷ 3.873 ]

or

Margin of error = ± 4.05

14. Suppose that the production of $1 million worth of steel in Canada requires $100,000 worth of taconite. Canada’s nominal tar
VMariaS [17]

Answer:

The effective rate of protection for Canada’s steel industry is 21%

Explanation:

The computation of the effective rate is shown below:

Steel percentage = (Production worth of steel) ÷ (Taconite worth)

                             = ($1,000,000) ÷ ($100,000)

                             = 10%

And the tariff rate for steel is 20%

And the taconite percentage is 10%

So, the effective rate would be equal to

= Tariff rate for steel + taconite percentage × steel percentage

= 20% + 10% × 10%

= 20% + 1%

= 21%

Assume that a country with an open economy has a fixed exchange-rate system and that its currency is currently overvalued in the
olasank [31]

Answer: b. The quantity of the country's currency supplied exceeds the quantity demanded.

Explanation:

A country operating a fixed-exchange rate system would be actively trading its currency to ensure that it remains at a certain rate. If the currency is overvalued, it means that the currency is actually weak and is being propped up by the company's actions in the forex market.

A reason for the weakness would be that the supply is higher than the demand of the currency which means that, as per the rules of supply and demand, the currency is trading at a lower price, i,e., it is weak.

ICE Princess25 [194]

Answer: Option (B) is correct.

Explanation:

The nominal GDP is equal to the real GDP in the base year, that's why GDP deflator in the base year is equal to 100.

GDP deflator is calculated as the nominal GDP divided by the real GDP multiply by 100. It is shown as:

GDP deflator = \frac{Nominal\ GDP}{Real\ GDP} \times 100

GDP deflator would be used as the conversion factor that transformed the real GDP into nominal GDP.
