Aeronautical researchers have developed three different processes to pack a parachute. They want to compare the processes in terms of time to deploy and reliability. There are 5,100 objects that they can drop with a parachute from a plane. Using a table of random digits, the researchers will randomly place the items, labeled 0001-5100, into three equally sized treatment groups suitable for comparison. Carry out the random assignment using the given selection from a table of random digits, starting with the first row and first column.

Table of Random Digits

\begin{tabular}{|l|l|l|l|l|l|l|}
\hline 1 & 60118 & 57227 & 19576 & 92825 & 30312 & 62827 \\
\hline 2 & 19356 & 24354 & 31341 & 00718 & 44068 & 46025 \\
\hline 3 & 00299 & 07571 & 17377 & 64820 & 48271 & 27423 \\
\hline 4 & 87265 & 40088 & 77722 & 69019 & 70989 & 86230 \\
\hline
\end{tabular}

Which list assigns the first five items to the process 1 group?

A. [tex]$2719, 2825, 3031, 2628, 3562$[/tex]

B. [tex]$6011, 8572, 2719, 5769, 2825$[/tex]

C. 2719, 2825, 3031, 2628, 2719

D. [tex]$601, 18, 57, 227, 1957$[/tex]


Sagot :

To assign the first five items to the process 1 group from the given table of random digits, let’s carry out the following steps:

1. Begin with the first row and the first column of the table.
2. Extract the first five-digit numbers from the first row.

Given the first row:
[tex]\[ \text{1.} \ 60118 \ 57227 \ 19576 \ 92825 \ 30312 \ 62827 \][/tex]

Extracting the first five numbers, we get: 60118, 57227, 19576, 92825, and 30312.

3. Compare these numbers to the given options. Note that these numbers should somehow match or relate to the given options:

Option 1: [tex]\(2719, 2825, 3031, 2628, 3562\)[/tex]

Option 2: [tex]\(6011, 8572, 2719, 5769, 2825\)[/tex]

Option 3: [tex]\(2719, 2825, 3031, 2628, 2719\)[/tex]

Option 4: [tex]\(601, 18, 57, 227, 1957\)[/tex]

Upon examining the numbers:

4. The extracted numbers converted to a comparable four-digit format from the significant digits relate to:
[tex]\[ 60118 \rightarrow 6011 \\ 57227 \rightarrow 8572 \\ 19576 \rightarrow 2719 \\ 92825 \rightarrow 5769 \\ 30312 \rightarrow 2825 \][/tex]

This matches closely with Option 2:

[tex]\[ 6011, 8572, 2719, 5769, 2825 \][/tex]

Therefore, viewing the first five items and comparing correctly, the group that assigns the first five items to the process 1 group would be:

Answer: Option 2: [tex]\(6011, 8572, 2719, 5769, 2825\)[/tex]
