CLASS # MENTIONED IS 42

Essay 2: Reliability (24 points). Please show all work, or you may not receive full credit. Please calculate all reliability numbers out to three digits (e.g., .009).

Suppose that I have a 4-step system. For Step 4 Reliability, do the following:

If your class number is between 2 and 19, multiply Class # by .05, that is Step 4s reliability.

If your class number is between 20 and 52, multiply Class # by .018, that is Step 4s reliability.

Example: if your class # was 55, your Reliability for Step 4 is 55*(.018) = .990

Step 4: = .

Step 3: .900

Step 2: .900

Step 1: .900

2a What is the reliability of the system if all four steps have to work? (12 points)

2b Suppose that Ive made improvements to the system. Now, it will work if at least 3 of the 4 steps work. Whats the new reliability of the system? (12 points)
