Sam wants to predict who will be selected as the seventh-grade student council representative. which of the following groups should sam survey to make his prediction? a. one hundred random students from the seventh grade b. one hundred random students from the entire school c. the first 100 students from an alphabetical list of seventh graders d. the first 100 students from an alphabetical list of the entire school

Option A is correct.

Step-by-step explanation:

Firstly, it is given that Sam wants to predict who will be selected as the seventh-grade student council representative. This signifies that a representative for 7th grade is needed, not for the entire school or any other class.

So, the best possible answer is option A: one hundred random students from the seventh grade.

Option B is wrong as representative is not needed for the entire school. Option C is not feasible as 100 students cannot be chosen from an entire population as it is a possibility that there cannot be many thousand students from 7th standard. option D is not true either as the representative is not needed for the school.
