The mean and variance of eight observations are 9 and 9.25, respectively. If six of the observations are 6, 7, 10, 12, 12 and 13, find the remaining two observations.

Explanation

To solve the problem, we need to find the two remaining observations given the mean and variance of eight observations, along with six known observations. Let's go through the solution step by step.

### Step 1: Understand the Given Information
We have:
- Mean (x̄) = 9
- Variance (σ²) = 9.25
- Six observations: 6, 7, 10, 12, 12, 13
- Let the remaining two observations be \( a \) and \( b \).
