To find out if there's a connection between how much people run and how many shoes they buy, we can look at the table and make a new one called a conditional relative frequency table. This table shows the parts of each group. For example, among the runners who go more than 5 miles a week, 42 buy more than 2 pairs of shoes, which is about 60% of them. But among the ones who run less than 5 miles, only 15 buy more than 2 pairs, about 32%. This shows that runners who go further buy more shoes, meaning there is likely a connection between running a lot and buying more shoes!
Use the table to answer the question.
Purchases More than 2 Pairs per Year
Purchases 2 Pairs or Less per Year
Total
Runs More than 5 Miles per Week
42 28 70
Runs Less than 5 Miles per Week
15 32 47
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 3–5 sentences.
