B· the 1,010 randomly selected adult Americans
C. 89% ofrandomly selected adult Americans
D. all adult Americans Identify the population

Answer 1

Answer: B· the 1,010 randomly selected adult Americans

Population = all adult Americans

Sample = the 1,010 randomly selected adult Americans

Sampling method = Simple random sampling

Explanation:

• The population is a group of members having similar characteristic by the researcher's point of interest.
• A sample is a finite-subset of the population. It represents the entire population , when population very large.

Given : In a Gallup poll of 1,010 randomly selected adult Americans, 89% said that cloning of-humans should not be allowed.

Here, Population = all adult Americans

Sample = the 1,010 randomly selected adult Americans

Because these 1,010 randomly selected adult Americans are representing the population of adult Americans.

Since , 1,010 people got selected randomly , so the method of sampling is simple random sampling as each adult American had the equal chance to get selected.

I think it is likely that the sample is representative of the population as when population very large we cannot do our research easily but to some extend sample gives a view of the entire population.
