Discuss the below:
Q1 In the U.S. legal system, a defendant is presume innocent until proven guilty. Consider a null hypothesis H o. that the defendant is innocent, and an alternative hypothesis H 1 that the defendant is guilty. A jury has two possible decisions: Convict the defendant(i.e., do not reject the null hypothesis). Explain the meaning of the risks of committing either a Type I or a Type II error in this example.
Q2 Suppose the defendant is presumed guilty until proven innocent as in some other judicial systems. How do the null and alternative hypotheses differ from those? What are the meanings of the risks of commiting either a Type I or Type II here?
