Answer:
No
Explanation:
Simple random sampling gives each member in the entire population an equal opportunity to be included in the sample. The technique removes bias in the selection procedure. It applies where a small number would adequately represent the entire population.
The procedure described in this case is a deviation of simple random sampling. It is stratified random sampling.
In stratified random sampling, the population is first divided into subgroups based on shared characteristics. The researcher uses simple random sampling to select representatives of each group in the sample population. The techniques ensure each group is fairly represented in the research.
Subdividing vehicles by their make is creating strata or subgroups.
Answer:
Answer for the question:
There are ten polluting firms, Firm1,. . . ,Firm10. Each firm emits 100 pounds of pollution prior to any regulations (so there are currently 1,000 pounds being emitted). Each firm has constant marginal abatement costs, but the costs vary across firms. Conveniently, the firms’ names indicate their marginal abatement costs. Firm1’s marginal abatement costs are constant at $1 per pound, Firm2’s marginal abatement costs are constant at $2 per pound,. . . , and Firm10’s marginal abatement costs are $10 per pound.
a. Suppose the regulator wants to achieve a 25% reduction in pollution (250 pounds). What is the cost effective allocation of emis- sions across the ten firms?
b. What are the total abatement costs for society to achieve a 250 pound reduction in emissions?
c. The marginal damage of pollution in this city is given by MD= 4-1/250 X, where X is the total reduction in pollution. What is the optimal level of pollution?
is given in the attachment.

Answer:
coupon payment = $2025
so correct option is A) $2,025
Explanation:
given data
par value = $100,000
coupon rate = 4%
annual inflation rate = 2.5% = 0.025
so Semiannual rate =
= 0.0125
to find out
coupon payment will the investor receive at the end of the first six months
solution
as we know principal would increase by the amount of inflation
so it will be = $100,000 ( 1 + 0.0125 )
so here coupon payment will as
coupon payment = $100,000 ( 1 + 0.0125 ) × 
solve it we get
coupon payment = $2025
so correct option is A) $2,025
Answer:
0.67
Explanation:
Opportunity cost is the cost of the next best option forgone when one alternative is chosen over other alternatives.
If the family buys one can of soup, the opportunity cost is the frozen food forgone.
Opportunity cost of one can of soup = 60 / 90 = 0.67

Answer:
Gross Impressions
Explanation:
Gross impressions represent the total number of households or individuals that is represented by a given media schedule. It is the impression that an advertisement gets. It is the total sum of audiences that is individuals or households that is exposed to the same commercial or program on multiple occasions. It is different to gross rating points. The latter deals with the number of impressions while the former deals with the number of audiences.
In this case, gross impressions
= Audience × number of ads
= 115000 × 16
= 1840000
