Find Number Groups with Mean Value 8: Average Selection Challenge

To solve this problem, we'll follow these steps to verify if each group of numbers has an average of 8:

• Calculate the average for each group of numbers provided in the answer choices.

Let's calculate:

• Choice 1: $10, 8, 12, 2$
  Sum = $10 + 8 + 12 + 2 = 32$
  Count = 4
  Average = $\frac{32}{4} = 8$
• Choice 2: $24, 0, 0$
  Sum = $24 + 0 + 0 = 24$
  Count = 3
  Average = $\frac{24}{3} = 8$
• Choice 3: $8, 8, 8$
  Sum = $8 + 8 + 8 = 24$
  Count = 3
  Average = $\frac{24}{3} = 8$

Therefore, all choices result in an average of 8.

This verifies that All answers are correct.
