Labelling
Kenny wanted to investigate the relationship between the number of people visiting a park in the winter and the number of people who played basketball at the park. He asked fifty people if they had visited the park in the winter and whether or not they had played basketball.
His data showed that 30 people had visited the park in the winter and 20 had not. Of the 30 who had visited the park in the winter, 24 had played basketball. Of the 20 who had not visited the park in the winter, 5 had played basketball there in the last year.
Construct a two-way frequency table showing this information.
