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?

random numbersimply means a number that occurs when it is impossible topredictit.treatments. In order to get treatment number, there must be three uniquerandom numbers.
