Answer: The minimum number of students you need if you want the margin of error to be 5% IS 278.
Explanation:
Cochran’s Sample Size Formula gives the minimum number of students as 
Where:
e is the desired level of precision (i.e. the margin of error),
p is the (estimated) proportion of the population which has the attribute in question and q is 1 – p.
The z-value for 95% confidence interval is found to be 1.96 in a Z table.
Assuming that half of the teenagers favor the elimination of a curfew: this gives us maximum variability. So p = 0.5 and q=0.5.
Then 
Rounding up, 
But considering that 1000 is a small population, we can modify the sample size we calculated above formula by using this equation:
Where s is the adjusted sample size, n is the original sample size we calculated and N is the population size.
Answer:
the amount that willing to pay is $44,591.11
Explanation:
The computation of the amount that willing to pay is as follows:
The Present Value of an Ordinary Annuity is
= Amount × [{1 - (1 ÷ (1 + rate of interest)^n} ÷ rate of interest]
= $1,000 × [{1 - (1 / (1 + 0.065 ÷ 4)^100} ÷ 0.065 ÷ 4]
= $44,591.11
Hence, the amount that willing to pay is $44,591.11
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
5.75%
Explanation:
Firstly, we need to find the yield-to-maturity (YTM) of current outstanding bond as below:
Bond market price = Coupon/(1 + YTM) + Coupon/(1 + YTM)^2 + Coupon/(1 + YTM)^3 +...+ Coupon/(1 + YTM)^20 + Face value/(1 + YTM)^20, or:
1,382.73 = 130/(1 + YTM) + 130/(1 + YTM)^2 + 130/(1 + YTM)^3 +...+ 130/(1 + YTM)^20 + 1,000/(1 + YTM)^20
Solve the equation, we get YTM = 8.85%.
So, if he company wants to issue new debt, its after-tax cost of debt is 8.85% x (1 - 35%) = 5.75%
Answer: 50 additional tons of hamburgers
Explanation:
United States opportunity costs:
Hamburger opportunity cost = 45/100 = 0.45 tons of tacos
Taco opportunity cost = 100/45 = 2.22 tones of hamburgers
Mexico opportunity cost:
Hamburger opportunity cost = 25/20 = 1.25 tons of tacos
Taco opportunity cost = 20/25 = 0.8 tones of hamburgers
US should specialize in Hamburger production because they have a lower opportunity cost.
If both countries combined production of hamburgers then the total would be:
= 100 + 20
= 120 tons of hamburgers
<em>There is missing information on this question which is the US production of hamburgers when it produces 0 tacos. We shall assume that number to be 170 tons of hamburgers.</em>
The total additional tons produced would be:
= US tons when producing only hamburgers - Combined hamburger production
= 170 - 120
= 50 additional tons of hamburgers
Answer:
Ur answer is that When the U.S. dollar is undervalued, the cost of a basket of goods in the United States is lower than the cost in Mexico when evaluated at the current exchange rate. To a U.S. tourist, Mexican goods and services would seem more expensive on average. Thus an undervalued currency will buy less in other countries.
