Ara's mean test score will increase the most because she consistently scored high in the previous tests, and receiving a perfect score on the latest test will significantly increase her mean score.

Sure, let's calculate the mean test scores for each of them:

Theo: (84 + 88 + 81 + 85 + 77 + 76) / 6 = 82.83
Ara: (100 + 98 + 99 + 97 + 100 + 100) / 6 = 99
Dana: (68 + 74 + 83 + 80 + 81 + 82) / 6 = 78
Jose: (91 + 93 + 97 + 96 + 96 + 96) / 6 = 95.83

We can see that Ara's mean score was already high but will increase by 1 point to 99. On the other hand, Jose's mean score will increase by 3.17 points to 95.83, making it the highest increase. Therefore, Jose's mean test score will increase the most.
