The conditional relative frequency table shows the distribution of shoe purchases within each running category. Runners who run more than 5 miles per week tend to purchase more pairs of shoes compared to those who run less than 5 miles per week. This suggests that there is an association between the distance run each week and the number of running shoes purchased annually, indicating that more frequent runners may require more footwear.

A running shoe company is collecting data on long-distance runners. The company’s research analyst asked runners how many pairs of running shoes they purchase each year and how many miles they run each week, on average. The results are summarized in the table. Determine if there is an association between the number of miles an individual runs per week and how many pairs of running shoes they purchase per year. Create a conditional relative frequency table of the data. Use your table to support your reasoning. Explain your reasoning in 3 simple sentences.
