This type of sampling method is called cluster sampling. With cluster sampling, the researcher divides the population into distinct group so called clusters. Then, a simple random sample of clusters is particular from the population. The researcher conducts his investigation on data from the sampled clusters. Paralleled to simple random sampling and stratified sampling, cluster sampling has advantages and disadvantages. For example, given equal sample sizes, cluster sampling usually makes available less precision than either simple random sampling or stratified sampling. On the other hand, if travel costs between clusters are high, cluster sampling may be further cost-effective than the other methods.
Answer:
cause no changes in the demand and supply curves of oil in the current year.
Explanation:
Changes in price don't generate shifts in the supply and demand curves in the short term. It generates a movement along the curves as non price changes are the ones that generate a shift in these curves. If the price of the oil increases, the demand quantity falls which will cause a movement along the demand curve. Also, this situation will increase the supply quantity which also generates a movement along the supply curve.
Galoshes increase their labor by 85.8% if there is a decrease in 37.4% in wages using elasticity of labor.
Elasticity of labor is defined as the percentage change in demand for labor to percentage change in demand for labor to percentage change in wage rate.
Elasticity of labor= % demand of labor/% change in wage rate
Let % wage decrease be x
Δ demand for labor =L
i) Galorhes R = ΔL/-Δx = -2.3
ii) Emerson R = ΔL/-ΔX= -3.2
III) Wayne= ΔL/-ΔX= 1.7
iv) Bull stearns = ΔL/-Δx= 4.6
Therefore, emerson,lake and palmer increases the amounts
Hence 2nd option
2) Galorhes R= ΔL--37.3=-2.3
= 37.3× 2.3
= 85.79%

Answer:
56.67%
Explanation:
Purchase cost = 30 dollars
Margin x price = 0.60x30 = $18
30-18 = $12
Profit = $47 - $30 - 0.07(12)
= 16.16
Percentage earned = (16.16 /18) * 100
= 89.78%
Profit from the trade
= 47-30
= 17
Percentage earned = 17/30 * 100
= 56.67%
The return would have been 56 67% if the investor had not done this.
This question is a little but more difficult to solve, as it depends on the situation. For certain banks it is not worth it due to rates that must be payed, but in your case here I believe that it would be TRUE.
