In a Past General Social Survey, a Random Sample of Respondents

In a past General Social Survey, a random sample of respondents answered the question "Are you a member of any sports groups?" Based on the sample data, 95% confidence intervals for the population proportion who would answer yes are 0.215 to 0.365 for people 18 to 23 years old and 0.247 to 0.333 for people 24 to 29 years old. Based on these results, you can reasonably conclude that

B) there is no conclusive evidence of a difference between the two age groups in the proportions of people belonging to sports clubs.
C) there is conclusive evidence of a difference between the two age groups in the proportions of people belonging to sports clubs.
