In problem 9, the bits are counted starting from zero. So we have the 0th bit, 1st bit, 2nd bit, 3rd bit, 4th bit, and so on. The problem is asking for the 4th bit.

Note on the Final Exam
The final was specifically designed so that you do not need CCS/Launchpad. All the answers can be found in the lessons and screencasts. You can use CCS/Launchpad if you like, but it will not give you much information (except for Prob. 8, which is very simple)
Typo in Prob. 20 of the Final
A typo in problem 20 has been corrected in the latest version of the final. Please download the current version from this website.
About the final
There will be no extension to the due date of the final exam, since finals will need to be graded, and grades set for about a hundred students, before the due date for grades submission set by the university. Depending on how closely you have been following the screencasts and lessons, the final exam may require a fair amount of searching through the lessons and screencasts. So please start working on the exam very soon and don’t wait till the last moment.

MT2 Hint correction
The corrected hint is:
inv.w with inc.w operations turns an operand into its two’s complement. For example,
“inv.w operand followed by inc.w operand”, will take the 2’s complement of the operand.
In the hint I posted, due to bad copy and paste, the bold faced part was missing. If you have already submitted your MT2 with the incorrect hint, then no points will be taken off your MT2.
