Find Groups with Mean = 6: Average Value Selection Problem

To solve this problem, we will apply the formula for the average. We will proceed by evaluating each choice to identify which group has an average of 6.

The average for a group of numbers is calculated as:

Now, let's calculate and analyze:

• Choice 1: $1,2,3$
  Calculate the sum: $1 + 2 + 3 = 6$
  Number of values: 3
  Average: $\frac{6}{3} = 2$

• Choice 2: $3,3,3$
  Calculate the sum: $3 + 3 + 3 = 9$
  Number of values: 3
  Average: $\frac{9}{3} = 3$

• Choice 3: $6,0,0$
  Calculate the sum: $6 + 0 + 0 = 6$
  Number of values: 3
  Average: $\frac{6}{3} = 2$

• Choice 4: $6,8,4$
  Calculate the sum: $6 + 8 + 4 = 18$
  Number of values: 3
  Average: $\frac{18}{3} = 6$

Thus, the group of numbers with an average of 6 is $6,8,4$.
