In the US legal system a defendant is presumed innocent unti

In the U.S. legal system, a defendant is presumed innocent until proven guilty. Consider a null hypothesis, Ho, that the defendant is innocent, and an alternative hypothesis, H1, that the defendant is guilty. A jury has two possible decisions: Convict the defendant (i.e. reject the null hypothesis) or do not convict the defendant (i.e. do not reject the null hypothesis).Explain the meaning of the risks of committing either a Type I or Type II error in this example.

Solution

Type 1 error is.....defendant is truely innocent...but we are rejecting that hypothesis and we are claiming that he is guilty.....
and
Type 2 error is....defendant is guilty...but we are accepting the hypothesis that he is innocent...
