This is my second time posting this same question because the first response I received on here was wrong. PLEASE PLEASE do not reply unless you are absolutely positive that you're right. If you do answer the question and you're wrong, I would greatly appreciate it if you would rework your problem until its correct.

The first answer from a Chegg expert that was WRONG was: Macaulay duration : 4.349 years These answers are INCORRECT!!!

Modified duration : 3.998 years
