Answer:

A. Observational study

Explanation:

An observational study measures the characteristics of a population by studying individuals in a sample, but does not attempt to manipulate or influence the variables of interest.

A designed experiment applies a treatment to individuals (referred to as experimental units or subjects) and attempts to isolate the effects of the treatment on a response variable.

Hence, we can see that proposed study is observational.

givi [52]

Answer:

Quantity of beef demanded will decrease by 12%

Explanation:

Data provided in the question:

Price elasticity of demand for beef, Ed = 0.60

Increase in the price of beef = 20%

Now,

Price elasticity of demand for beef,

Ed = [ Percentage change in Quantity ] ÷ [ Percentage change in price  ]

or

0.60 = [ Percentage change in Quantity ] ÷ 20%

or

Percentage change in Quantity = 0.60 × 20%

or

Percentage change in Quantity = 12%

Also,

Price and Quantity are inversely proportional

Hence,

With the increase in price, the quantity will decrease

Therefore,

Quantity of beef demanded will decrease by 12%
