Consider the problem facing security personnel at a military facility in the Southwest. Their job is to detect infiltrators (spies trying to break in). The facility has an alarm system to assist the security officers. However, sometimes the alarm doesn't work properly, and sometimes the officers don't notice a real alarm. In general, the security personnel must decide between these two alternatives at any given time:
H0: Everything is fine; no one is attempting an illegal entry.
H1: There are problems; someone is trying to break into the facility.
Based on this information, fill in the blanks in these statements:
a. A "missed alarm" is a Type ___ error, and its probability of occurrence is denoted as ___.
b. A "false alarm" is a Type ___ error.
