What was the age range of participants in the initial study of concert ticket pricing?

• A. 18-60
• B. 18-31
• C. 21-50
• D. 15-75

Answer: (A)

The age range sets who was actually studied, which in turn shapes how the results apply to real people. In this study, participants were adults from 18 to 60 years old, capturing younger and middle-aged adults while excluding younger teens and older seniors. This matters because the responses to concert ticket pricing can differ across age groups, so knowing the exact range tells you which populations the findings describe.

Among the options, the range 18-60 matches the study's sample precisely. The other ranges either cut off part of the actual sample or include ages outside it (for example, including minors or people over 60), which would misalign with the study's reported data.
