How's this answer wrong? Write the statement as an equivalent statement that does not use the if..then connective. Remember that $p\implies q \equiv \neg p\land q$. If i am tired, then I'm going to bed.
I am not tired and I'm going to bed. 

I think you have it a little mixed up. Instead of a conjunction, you should have a disjunction.
It should read: I am not tired or I'm going to bed.
