MHB Decoding an Even-Parity SECDED Character

[DeathDealer]

Hey guys it feels like I'm banging my head against the wall when it comes to these types of questions. My tutor helped me out with a question but he didn't explain it to well he just wrote all he was doing down and expected me to know every single thing. I had to go through textbooks galore to understand half of it and I don't even know if we got it right in the end, needed tons of help. Now when i look at a similar question all I see is further confusion. Can someone help me out with this question and tell me if they think the one my tutor helped me with was right. I am sure after 2 examples ill be able to get my bearings. Cheers!

Question: An even-parity SECDED encoded character has been retrieved, with hexadecimal value View attachment 4304. Was there an error? If there was an error correct it (reporting corrected ASCII character) or explain why it couldn’t be corrected.This is the one my tutor "helped" me with:

Hi RobJob! Welcome to MHB! :)

The explanation of your tutor seems fine to me.
Where are you stuck?
Perhaps you can start by splitting BEB₁₆ into the same table?
