Hmm. I tried getting the latest version of this file and it doesn’t have this typo, so possibly you happened to get your copy at just the wrong time, and the problem has now been fixed.  
You could try getting the latest copy of the assignment, but probably easiest would be to just make the cell editable and fix the typo. To make the cell editable, put your cursor in the cell and:

- Choose “Cell toolbar/Edit metadata” from the View menu
- Then click the “Edit metadata” button in the cell and change “editable” to true
