Answer 2

Answer:

Arithmetic mean = 14.56

Step-by-step explanation:

Arithmetic mean = (Sum of product of age & number of students / Total number of students)

Arithmetic mean = {(12x4) + (13x3) + (14x5) + (15x6) + (16x2) + (17x5)} / (4+3+5+6+2+5)

Mean = (48 + 39 + 70 + 90 + 32 + 85) / 25

Mean = 364/25

Mean = 14.56
