The size of the sample that must be used is 264. The correct sample size is 264. Read below about how to arrive at the sample size.

<h3>What is the sample size that must be used?</h3>

p′ = x / n where x represents the number of successes and n represents the sample size. The variable p′ is the sample proportion and serves as the point estimate for the true population proportion.

Then, it follows that,

p= 30/10 x 88 = 264

Therefore, the correct answer is 264.

What is Oligopoly?

In Oligopoly markets, a limited number of suppliers control the market. They are present in every nation and a wide variety of industries.

A company enters into a short futures contract to sell 25,000 units of a commodity for 950 cents per unit. The initial margin is
Ksju [112]

Answer:

$958

Explanation:

The amount that is excess in the initial margin account can be withdrawn. So we calculate the price increase that will result in a $2000 increase in initial margin.

The present price per unit of the commodity is 950 cents for 25,000 units

A unit increase of the price (which is in cents) will be 1/100= 0.01

Therefore an increase in price of 0.01 will lead to gain of 0.01 * 25,000= $250

Let's get price increase that will result in $2,000 gain

$250 = 1 unit price increase

$2,000 = x

x= (2000 * 1) ÷ 250= 8 units increase

Therefore the price at which $2,000 can be withdrawn is 950 + 8= 958 cents

Suppose the United States decides to reduce export subsidies on U.S. agricultural products, but it does not decrease taxes or in
Ann [662]

Answer:

1. Decrease, increase

2. Supply curve shifts to the right

3. NCO will rise

4. Real exchange rate falls and net exports rises

Explanation:

Fiscal deficit occurs when government spending's exceed government revenue. When the government lowers its export subsidies while keeping other spending's and taxes unchanged, it leads to a fall in the fiscal deficit.

1. However, the reduction in expenditure on export subsidies <em>decreases</em> the fiscal deficit, thereby <em>increases </em>public savings.

2. As public savings increase it leads to an increase in funds available to be loaned out. So the <em>supply curve</em> for loanable funds will <em>shift to the right</em> from S1 to S2. This will lead to a <em>fall</em> in the interest rate.

3. As we know that net capital outflow is inversely related to the interest rate. A fall in the interest rate above will lead to a <em>rise</em> in net capital outflow.

4. When net capital outflow increases, people move funds out of the country. Thus, supply of dollars will increase. While demand for dollars has remained unchanged, it leads to a<em> fall</em> in the real exchange rate. As exchange rate falls, the equilibrium level of net exports will <em>rise</em>.
