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:
$2,000
Explanation:
The computation of the profit in case of Product B processed further is shown below:
Sales value if processed further $35,000
Less: Sales value at Split-Off $30,000
Incremental revenue $5,000
Less: Additional costs $3,000
Incremental income $2,000
First we have to find out the incremental revenue after that deduct the additional cost so that the incremental income or we can say profit could arrive
Answer:
Instructions are listed below
Explanation:
Giving the following information:
The Variable unitary cost= $37 each.
The fixed costs are $70,000.
The selling price for each product is $72.
1) revenue function= P*X
Revenue function= 72*x
Option E
2) Profit function= (P-Vc)*X-Fc
Profit function= 35*x-70000
Option B
3) break-even quantity= fixed costs/contribution margin
break-even quantity= 70000/35= 2000 units
Option D
4) break-even point ($)=fixed costs/contribution margin ratio
Contribution margin ratio= contribution margin/P= 0,49
break-even point ($)=70000/0,4861111= $144000
I think the correct answer from the choices listed above is option A. The loan type that requires you to make loan payments while you’re attending school would be unsubsidized federal loan. For this type, y<span>ou are responsible for paying the interest on a Direct Unsubsidized Loan during all periods. Hope this answers the question.</span>
