Answer:

The proportions that are most useful in analyzing the relationship between age and tattoos are 170/230 and 320/765.

When analyzing the relationship between age and tattoos, it is essential to consider the proportions that compare the prevalence of tattoos in different age groups. In this case, the survey conducted by students yielded the following proportions:

170/230 and 60/230

170/490 and 445/505

170/230 and 320/765

170/490 and 60/505

By focusing on the topic of whether younger adults are more likely to have tattoos, the most relevant proportions to analyze the relationship between age and tattoos would be those comparing the prevalence of tattoos in younger adults and older adults. Therefore, the proportions 170/230 and 320/765 are the most useful in this context.
