To find out whose mean test score will increase the most, we need to calculate the average of each student's previous test scores and compare it to their current average with the latest test score included.
Theo's previous mean test score = (84 + 88 + 81 + 85 + 77 + 76) / 6 = 83.5
Theo's new mean test score = (83.5 + 100) / 7 = 88.57
Jose's previous mean test score = (91 + 93 + 97 + 96 + 96) / 5 = 94.6
Jose's new mean test score = (94.6 + 100) / 6 = 98.1
Dana's previous mean test score = (68 + 74 + 83 + 80 + 81 + 82) / 6 = 78.0
Dana's new mean test score = (78.0 + 100) / 7 = 85.1
Ara's previous mean test score = (100 + 98 + 99 + 97 + 100 + 100) / 6 = 98.3
Ara's new mean test score = (98.3 + 100) / 7 = 98.47
Therefore, Jose's mean test score will increase the most, from 94.6 to 98.1, with an increase of 3.5 points.
Theo, Ara, Jose, and Dana all got 100 percent on their latest math test. Their scores on the previous six tests are listed. Whose mean test score will increase the most?(1 point) Responses Theo: 84, 88, 81, 85, 77, 76 Theo: 84, 88, 81, 85, 77, 76 Jose: 91, 93, 97, 96, 96 Jose: 91, 93, 97, 96, 96 Dana: 68, 74, 83, 80, 81, 82 Dana: 68, 74, 83, 80, 81, 82 Ara: 100, 98, 99, 97, 100, 100
