Please provide complete workup detail. Thank you.

Work out: Suppose we want an error correcting code that will allow all single- bit errors to be corrected for data of length 11. How many check bits are necessary? a. b. Suppose we are now working with data of length 8. The length of all code words will be 12. We now receive the following code word: 010111101110 Is this legal code word, assuming odd parity? If not, where is the error
