In your question, we're to suppose a defendant in a particular judicial system is presumed guilty until proven innocent.
00:07
We are first to determine what the null and alternative hypotheses are.
00:12
Now, it appears to me that you already have done that, and you've done it correctly.
00:16
H sub 0 is the defendant is guilty, and the alternative hypothesis, h sub 1, is the defendant is innocent.
00:44
So that looks to be completed.
00:45
We're moving on here now to part two and we're to determine the meanings and the risks of committing a type 1 or type 2 error.
00:55
So let's talk quickly about a type 1 error and what it means.
01:00
A type 1 error is often called a false positive and it means that you reject a true null.
01:15
Type 2 error is often called a false negative and a way of thinking about that is not rejecting a false null all right so now we want to look at your answer choices and see if we can determine what they would mean in the way that your answer choices are written so rejecting for a type 1 we're going to reject a true null.
02:02
So that means we're rejecting this, we're finding the person innocent when in fact they were guilty.
02:11
So type 1 in this context would mean not convicting a guilty person because we rejected the null, but the null was true and the null is about being being guilty...
