A sample of public health volunteers in a training program was sorted into a two-way table. Rows are training route (online route; field route) and columns are certification result (passed the certification quiz; did not pass the certification quiz). Counts: online route with passed the certification quiz: 36; online route with did not pass the certification quiz: 41; field route with passed the certification quiz: 29; field route with did not pass the certification quiz: 53. Row totals: online route: 77; field route: 82. Column totals: passed the certification quiz: 65; did not pass the certification quiz: 94. Grand total: 159. What is the absolute difference between P(passed the certification quiz given online route) and P(passed the certification quiz given field route)?
