Which of the following statements is true?
Solution
Solution Steps
Step 1: Identify the Crates Selected for Inspection
Using the provided random digits \( 7480312009452877175398230664198453311793049512059711384 \), we read from left to right to select crates numbered from 1 to 9. The unique digits corresponding to the crate numbers selected for inspection are \( 8, 3, 4, \) and \( 7 \).
Step 2: Map Crate Numbers to Company Names
The selected crate numbers correspond to the following companies:
\( 8 \) corresponds to Foxwood
\( 3 \) corresponds to Sapphire
\( 4 \) corresponds to Dallhoise
\( 7 \) corresponds to Cherryport
Final Answer
The companies selected for close inspection are:
