Show answer & explanation
Correct answer: C
Key idea: adding the same number to every value increases the average by that number.
Compute the original total: 16 × 8 = 128.
Adding 2 to each of the 16 numbers increases the total by 16 × 2 = 32, so the new total is 128 + 32 = 160.
New average = 160 ÷ 16 = 10.
Answer: 10
