Q1 In connection with a program that provides alternatives for youth who have a run in with the criminal justice system, a colleague mentions that the program could be more effective if there were an easy way to predict who might benefit from the alternative program. The data suggests that about 75% of the youth in Ourtown are "good kids" who would benefit from the alternative program and 25% are "bad kids" who will not. Your supervisor also says you should come up with some more acceptable terms than "good" and "bad."
It turns out that when a kid is, in fact, "bad," the test gets it right 90% of the time, wrong 10%. But when the kid is, in fact, "good," the test says "bad" 30% of the time.12. Sketch an event tree that captures this and then flip the tree to evaluate the test and provide guidance on how to interpret its results.
