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.

Which design is the most appropriate for this
experiment?
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.
O Randomly number each item with 1, 2, or 3. Assign
the items labeled 1 to the process 1 group, assign
the items labeled 2 to the process 2 group, and
assign the items labeled 3 to the process 3 group.
O Number each item from 1 to 1,200. Reading from
left to right from a table of random digits, identify
800 unique numbers from 1 to 1,200. Assign the
items with labels in the first 400 numbers to the
process 1 group. Assign the items with labels in the
second 400 numbers to the process 2 group.
Assign the remaining items to the process 3 group.
O Number each item from 0000 to 1199. Reading
from left to right on a random number table, identify
800 unique four-digit numbers from 0000 to 1199.
Assign the items with labels.in the first 400
numbers to the process 1 group. Assign the items

first digit is a 1, 2, or 3, assign the item to the
process 1 group. If the first digit is a 4, 5, or 6,
assign the item to the process 2 group. If the first
digit is a 7, 8, or 9, assign the item to the process 3
group. If the first digit is a 0, skip that digit and
move to the next one to assign the item to a group.
Repeat this process for each item.
