Answer and Explanation:

A. The point estimate of individuals that would provide yes responses is the sample proportion. The sample proportion is calculated by dividing number of yes responses by sample size:

p = x/n = 200/700= 0.2857

B. The standard error of the population is the square root of the product of the point estimate and it's complement divided by the sample size given by

√p(1-p)/n

=√0.2857(1-0.2857)/700= 0.0170

C. For confidence level 95%, z score is calculated 1-0.95= 0.05/2= 0.025

Z score checked under the table = 1.96

Boundaries=

P-1.96 *standard error and p+1.96 *standard error

= 0.2857-1.96*0.0170= -0.25238

=0.2857+1.96*0.0170= 0.31902

Note : BODMAS demands we multiply first in the above calculation before subtraction or addition.

What effect does an expansionary monetary policy in the u.s. have on the foreign trade sector?
Lostsunrise [7]

The lower value of the dollar will decrease imports and increase exports. Appreciation of the value of the dollar and the decrease of U.S. net exports.

<h3 /><h3>How does expansionary monetary policy affect trade?</h3>
  • Increases in the stock market are a result of expansionary economic policy since it boosts economic activity. Fiscal and monetary channels can be used by policymakers to carry out an expansionary strategy. It is typically used when inflationary pressures are low and the economy is headed towards a recession.
  • When a central bank employs an expansionary monetary policy, it helps to boost the economy. This boosts the availability of money, brings down interest rates, and raises demand. It promotes economic expansion. It reduces the currency's worth, which decreases the exchange rate.
  • The following are the general effects of monetary policy on economic activity, as measured by changes in (real) interest rates. Financial institutions can obtain funds at cheap interest rates when interest rates fall. They are able to lower their lending rates for loans to businesses and households as a result.
  • Expansive monetary policy can be quite successful in the early stages of a financial and economic collapse, reducing uncertainty spikes and tail risks and preventing negative feedback loops (e.g. Mishkin 2009).

Suppose the price of apples goes up from $20 to $22 a box. In direct response, Goldsboro Farms supplies 1,200 boxes of apples in
OLga [1]

Answer:

A

Explanation:

Price elasticity measures the responsiveness of the quantity demanded or supplied of a good to a change in its price. It is computed as the percentage change in quantity demanded—or supplied—divided by the percentage change in price.

Elasticity can be described as elastic—or very responsive—unit elastic, or inelastic—not very responsive.

Elastic demand or supply curves indicate that the quantity demanded or supplied responds to price changes in a greater than proportional manner.

An inelastic demand or supply curve is one where a given percentage change in price will cause a smaller percentage change in quantity demanded or supplied.

Unitary elasticity means that a given percentage change in price leads to an equal percentage change in quantity demanded or supplied.

Vlad1618 [11]

Answer:

The unemployment rate is 42.85.

Explanation:

The formula to calculate the unemployment rate is:

Unemployment Rate = (Unemployed People / Total Labor) x 100 -- (1)

where total labor is the sum of the unemployed people and employed people.

Unemployed People = 10 Retired persons + 5 stay-at home parents + 10 persons with no job + 5 persons who wanted job

Unemployed People = 30

Labor Force = Employed people + Unemployed people

Labor Force = 40 + 30

Labor Force = 70

Putting the values in equation 1,

Unemployment Rate = ( 30/ 70) x 100

Unemployment Rate = 42.85

Cost of Debt. Micro Spinoffs Inc. issued 20-year debt a year ago at par value with a coupon rate of 8%, paid annually. Today, th
stealth61 [152]

Answer:

5.925%

Explanation:

For computing the cost of debt, first we have to determine the YTM by using the Rate formula that is shown in the attachment

Given that,  

Present value = $1,050

Assuming figure - Future value or Face value = $1,000  

PMT = 1,000 × 8%  = $80

NPER = 20 year - 1 year = 19 year

= Rate(NPER;PMT;-PV;FV;type)  

The present value come in negative  

So, after solving this,  

1. The pretax cost of debt is 7.50%

2. And, the after tax cost of debt would be

= Pretax cost of debt × ( 1 - tax rate)

= 7.50% × ( 1 - 0.21)

= 5.925%
