Final answer:
Only conclusion C is valid, indicating that 15% of the baseball team members at Ridgemont High School like broccoli; all other options inaccurately extend the survey results beyond the specific group surveyed. Option C is correct.
Step-by-step explanation:
The Wholesome Food Company surveyed students on the baseball team at Ridgemont High School about their liking of broccoli and found that 15% said "Yes." Only the baseball team was surveyed, so the results cannot be generalized to the entire school or to students who play different sports or do not play sports at all. Therefore, the only valid conclusion from the provided options is:
(C) 15% of students on the baseball team at Ridgemont High School like broccoli.
Conclusions A, B, and D are invalid because they extend the survey results beyond the specified group without evidence. The survey did not include all students at the school, students from other sports teams, or students who do not participate in sports. The data only reflects the preferences of the baseball team members who were surveyed.
