The conditional relative frequency table was calculated by row using data from a survey of one station’s television programming. The survey compared the target audience with the type of show, either live or recorded, over a 24 -hour time period. Television Programming Live Recorded Total Adult 0 point 6 2 5 0 point 3 7 5 1 point 0 Children 0 point 5 0 point 5 1 point 0 Total almost equal to 0 point 5 8 3 almost equal to 0 point 4 1 7 1 point 0 Which is the best description of the value 0 point 3 7 5 in the table?
Answer
A
Given that the program was targeted at adults, there is a 37 point 5 percent chance that it was recorded.
B
37 point 5 percent of the programs are recorded.
C
Given that the program was recorded, there is a 37 point 5 percent chance that it was targeted at adults.
D
37 point 5 percent of the programs are targeted at adults.
Explanation
The table gives conditional relative frequencies calculated by row, so the adult row describes programs given that they target adults. In that row, the recorded value is 0.375, which is 37.5%. Therefore, given that a program was targeted at adults, there is a 37.5% chance it was recorded.
