We know that the young woman's study group consists of students from three categories: 
- 7 percent from the town where the school is located
- 80 percent from in-state (but not from the school's town)
- The rest are from outside the state.

Since percentages must add up to 100, we can find the percentage of students from outside the state by subtracting the sum of the percentages of the other two categories from 100:

100% - 7% - 80% = 13%

Therefore, 13% of the study group students are from outside the state, which is answer choice E.
