In the North American court system a defendant is assumed in

In the North American court system, a defendant is assumed innocent until proven guilty. In an ideal world, we would expect that the truly innocent will always go free, whereas the truly guilty ones will always be convicted. Now, let us tackle the following questions: 1. In the context of the Type I error and Type II error, can you relate a court trial scenario in terms of these two errors? 2. What would be your ideal situation if you are the defendant? 3. What would be your ideal situation if you are the prosecuting attorney?

Solution

Type I error is when wrong assumption is failed to reject. Means defendent innocent but it has failed to prove it and he/she is convicted.

Type II error is when wrong alternative hypothesis is accepted. Means defendent is guilty but it has failed to prove it and he/she is innocent.

Type one error is ideal situation for defendent.

Type II error is ideal for prosecuting.
