Answer :
Final answer:
The size of the sample in question is 40, the number of representatives surveyed by the political scientist. The size of the population — the total number of representatives in the congress — is 122.
Explanation:
The size of the sample is the number of representatives that the political scientist surveyed, which is 40, so the answer is a) 40. This sample is a portion selected from a larger group, also known as a population. The population, in this case, is the total number of representatives in the state's congress, which is 122, making the answer c) 122.
This concept is a key principle in statistics, where researchers often use a sample size to infer information about a larger population. It's a practical approach used in fields like political science because it's often impractical or impossible to gather data from the whole population. It's important, though, that the sample is accurately representative of the larger population to obtain valid results.
