To calculate the weighted mean, we need to first calculate the total grade points earned and then divide by the total credit hours for the semester.

For this student,

Grade points for History (B): 3 x 5 = 15
Grade points for Statistics (A): 4 x 4 = 16
Grade points for Spanish (C): 2 x 3 = 6
Grade points for English (C): 2 x 5 = 10

Total grade points earned = 15 + 16 + 6 + 10 = 47
Total credit hours = 5 + 4 + 3 + 5 = 17

Weighted mean = total grade points earned / total credit hours = 47 / 17 = 2.76

Therefore, the answer is C.
