Answer 1

Ara's mean test score will increase the most.

Explanation:
- Dana's mean test score: (68+74+83+80+81+82)/6 = 78
- Ara's mean test score: (100+98+99+97+100+100)/6 = 98.33
- Theo's mean test score: (84+88+81+85+77+76)/6 = 82.83
- Jose's mean test score: (91+93+97+96+96+96)/6 = 94.83

Since Ara got a perfect score on the latest test, their mean test score will increase the most.
