A prisoner on trial for a felony is presumed innocent until proven guilty. (That is, innocent is the null hypothesis.) Which of the following represents the risk involved in making a Type II error?
A. The prisoner is actually guilty and the jury sets him free.
B. The prisoner is sent to jail.
C. The prisoner is actually innocent and the jury sets him free.
D. The prisoner is actually guilty and the jury sends him to jail.
E. The prisoner is actually innocent and the jury sends him to jail.
E. The prisoner is actually innocent and the jury sends him to jail.
This represents the risk of a Type II error, where the null hypothesis (prisoner is innocent) is not rejected when it is actually false.
