Answer:
E. Cluster
Explanation:
Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population clusters. The analysis of such population is carried out based on the sampled clusters.
This method is adopted when a researcher does not have access to the whole population under research.
Advantages of cluster sampling.
The research method only needs fewer resources.
The sample under review is feasible.
Note: Cluster sampling is not as accurate as simple or stratified random sampling.
Answer:
“Should” or “should not” depend on the cost rate of the option and the risk appetite of investors.
Explanation:
An option is a contract that allows investors to buy or sell instruments such as security, Exchanged Traded Fund or an index at a pre-determined price over a certain period of time.
If the option will cost the investor an additional $10,000 and it is the cost for an option of $10 million investment, then it cost only 0.1% additionally, but it can secure the position of this investment; then the investor should buy this option.
Vice versa, if the additional $10,000 is much more than expected profit, and even lower but significantly drop down the total profit of an investment; and the investor always wish to have a high profit regardless high risk; then he shouldn’t buy this option.
Answer:
1. $636
2. $674.16
3. $566.04
4. $534
Explanation:
PV = FV ÷ (1 + r/n)^(t × n)........(1)
PV = present value
FV = Future value
r = rate per period
t = number of years
n = number of compounded period per year
FV = P(1 + r/n)^(t×n)...............(2)
FV = Future value
P = principal
r = rate per period
n = number compounded period per year
t = number of year
NO 1.
P= $600
t = 1
n = 1
r = 6% = 0.06
Using equation 2
FV = 600(1 + 0.06/1)^(1 × 1) = $636
NO 2
P = $600
n = 1
t = 2
r = 0.06
Using equation 2
FV = 600(1 + 0.06/1)^(2 × 1) = $674.16
NO 3.
FV = $600
r = 0.06
t = 1
n = 1
Using equation 1
PV = 600 ÷ (1 + 0.06/1)^(1 × 1) = $566.04
NO 4.
FV = $600
r = 0.06
n = 1
t = 2
Using equation 1
PV = 600 ÷ (1 + 0.06/1)^(2 × 1) = $534
Answer: A Contract was formed on February 5th
Explanation:
The contract was formed the very day that Bob mailed Ann his acceptance which was on the 5th of February.
Ann attempted to revoke the acceptance too late as she did it a day after he had emailed his acceptance even though she only received it on the 7th.
The date she received the acceptance is of no consequence because this falls under the Posting Rule. This rule in Common Law countries essentially states an agreement is made as soon as the letter is posted even if it never gets to it's destination.
Answer:
D. The breakeven point decreases.
Explanation:
Breakeven point of a business is defined as the point where it's total cost and total revenues are equal, at this point there is no gain or loss. Hen revenue is above this point profit is made, and when revenue is below this point there is loss.
The formula for break-even is
Breakeven point= Total fixed cost/(Sales price per unit- Variable cost per unit)
Since sales price and variable cost is constant, let's say
(Sales price per unit- Variable cost per unit)= constant (k)
So when we cross-multiply in the formula
Breakeven* k= Total fixed cost
It shows that Breakeven point is directly proportional to Total fixed cost.
So a reduction in Total fixed cost will result in a reduction in Breakeven point.
