Answer 2

Answer:

6.85

Step-by-step explanation:

Observations = 10, 7, 5, 3, 8, 6, 9

Number of Observations = 7

Sum of observations = 48

We know that,

$\text{Mean} = \dfrac{\text{Sum of observations}}{\text{Number of observations}}$

Applying in the formula we get,

$\text{Mean} = \dfrac{48}{7} = 6.85$

Hence the mean is 6.85
