Answer: 89.7
Step-by-step explanation:
The mean of a data set is the average of all the information given. Therefore, the total combined score is the number of students multiplied by the mean
The total score of the first 44 students: 96.6*44 = <em>4250.4</em>
The total score of the later 13 students: 66.3*13 = <em>861.9</em>
(4250.4 + 861.9)/(44 + 13) = 89.7
