Answer: Simple random
Explanation: In statistics, a simple random sample is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability .In this technique, each member of the population has an equal chance of being selected as subject. The entire process of sampling is done in a single step with each subject selected independently of the other members of the population. Simple random sampling is a method used to cull a smaller sample size from a larger population and use it to research and make generalizations about the larger group . Simple random sampling is the most basic and common type of sampling method used in quantitative social science research and in scientific research generally.
The factor that would shift demand is the reduction in the price of laptops.
The equilibrium price and quantity would decrease.
<h3>What is the result of the policy?</h3>
When the price of laptops are reduced, the quantity demand for laptops would increase while the demand for computers would fall. This is because computers and laptops are substitute goods.
As a result of a fall in the demand for computers, the demand curve would shift to the left. Equilibrium price and quantity would fall.
