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? 3 400 800 1,200

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? 3 400 800 1,200

Answer

Answer:

1,200

Explanation:

Step1: Determine group - size

Since there are 1200 items to be divided into 3 equally - sized groups, each group has $\frac{1200}{3}=400$ items.

Step2: Identify number of random numbers

To randomly assign all 1200 items to the 3 groups, we need to select a random number for each of the 1200 items. So, 1200 unique random numbers need to be selected from the table of random digits.
