Type 1 error is when you reject the null hypothesis even though it is true. T/F ---
ANSWER--- True
TRUE or FALSE? 𝛼=𝑃(𝑅𝑒𝑗𝑒𝑐𝑡𝐻0|𝐻0𝑖𝑠 𝑡𝑟𝑢𝑒) is the probability of a Type I error. ---
ANSWER--- True
Type 2 error is when you accept the null hypothesis even though it is false. T/F ---
ANSWER--- True
(ARENA) TRUE or FALSE? You can change the number of servers on duty (i.e., the
capacity) for a resource using the Resource spreadsheet. ---ANSWER--- TRUE
(ARENA) TRUE or FALSE? You can a queue discipline from FIFO to LIFO with one
click by using the Queue spreadsheet. ---ANSWER--- TRUE
(ARENA) TRUE or FALSE? A process is generally considered to consist of both a
resource and its associated queue. ---ANSWER--- TRUE
What is the name of Arena's primary modeling approach "world view"?
A) Process-Interaction
B) Event-Scheduling
C) Continuous Modeling Flowchart
, D) Mixed Modeling
E) Event-Interaction ---ANSWER--- A) Process Interaction
What sequence of Arena modules would you use to
generate customer arrivals, use a server
, and then have customers leave the system
after they're done with the server? ---ANSWER--- Create-Process-Dispose
(ARENA) TRUE or FALSE? A Create module allows you the use a variety of customer
interarrival time distributions. ---ANSWER--- TRUE
(ARENA) What is Seize-Delay-Release? ---ANSWER--- Grab at least one resource
(server), spend time getting served, and then free the server for the next customer. If
you seize and the server isn't available, you may have to wait in a queue.
(ARENA) What is a seize-delay? ---ANSWER--- Grab at least one resource and spend
time getting served. Remember to release the server sometime later, else he gets
deadlocked and a giant line will form.
(ARENA) What is a delay-release? ---ANSWER--- Use a previously seize'd for a while,
and then free him for the next guy to use.
(ARENA) Which of the following action sequences can you find in a Process module?
A) Delay
B) Seize-Delay
