B. Flawed sampling method
C. Depends on the age group surveyed
D. Cannot determine without response rate information

Answer 1

The sampling method used in the survey of beliefs about evolution conducted by Gallup pollsters appears to be sound. They employed simple random sampling by randomly selecting and telephoning 1018 adults in the United States.

Step-by-step explanation:

The sampling method appears to be a sound sampling method for the survey of beliefs about evolution conducted by Gallup pollsters.

They randomly selected and telephoned 1018 adults in the United States, which is a form of simple random sampling.

Simple random sampling ensures that every individual in the population has an equal chance of being selected, allowing for generalizations about the larger population.

Without response rate information, it is not possible to determine whether the sampling method is sound or flawed.
