Aeronautical researchers have developed three different processes to pack a parachute. They want to
compare the different processes in terms of time to
deploy and reliability. There are 1,200 objects that they
can drop with a parachute from a plane. Using a table
of random digits, the researchers will randomly place
the 1,200 items into three equally sized treatment
groups suitable for comparison. How many unique random numbers need to be
selected from the table of random digits?
0 3
O 400
O 800
O 1,200
