The conditional relative frequency table was generated using data that compared the cost of one ticket for a performance and the method by which the ticket was purchased.
A 4-column table with 3 rows titled ticket purchases. The first column has no label with entries purchased online, purchased at the box office, total. The second column is labeled no more than $30 with entries 0.7, 0.3, 1.0. The third column is labeled more than $30 with entries 0.86, 0.14, 1.0. The fourth column is labeled total with entries 0.82, 0.18, 1.0.
