Answer:
Observational study
Explanation:
The study shown in the question above is an example of an observational study. In this type of study, the researcher separates two groups of people, where the variables will be tested. These groups are contrasting with each other, which promotes the comparison on how the variables behaved in each group.
In the study shown in the question above, the researcher should separate the groups between right-handed and left-handed people and make assessments of how it affects their health, decreasing the life expectancy of each one.

A price ceiling is a government- or group-imposed price control, or limit, on how high a price is charged for a product, commodity, or service. Governments use price ceilings to protect consumers from conditions that could make commodities prohibitively expensive. Such conditions can occur during periods of high inflation, in the event of an investment bubble, or in the event of monopoly ownership of a product, all of which can cause problems if imposed for a long period without controlled rationing, leading to shortages.[1] Further problems can occur if a government sets unrealistic price ceilings, causing business failures, stock crashes, or even economic crises. In unregulated market economies, price ceilings do not exist.
While price ceilings are often imposed by governments, there are also price ceilings which are implemented by non-governmental organizations such as companies, such as the practice of resale price maintenance. With resale price maintenance, a manufacturer and its distributors agree that the distributors will sell the manufacturer's product at certain prices (resale price maintenance), at or below a price ceiling (maximum resale price maintenance) or at or above a price floor.
