Question 1169340
To reject Ho when it is not true is what we want to do.
To not reject Ho when it is true is what we want to do.
-
We don't want to reject Ho in error, say Ho is wrong when it isn't. That is saying someone is guilty when he isn't.  Here, that is bad.
-
We don't want to accept a false null hypothesis.  We don't want to say something is acceptable when it is not.
-
So, we would want to be exceptionally certain NOT to kill an innocent person, and a very high significance level is required.
-
That is D.
P{reject Ho|Ho true} should be small. Call the defendant guilty when he is innocent should be small.
