Extract the data values from the graph

\[

$$\begin{aligned} &\text{Monday} = 6\\ &\text{Tuesday} = 2\\ &\text{Wednesday} = 3\\ &\text{Thursday} = 4\\ &\text{Friday} = 10 \end{aligned}$$

\]

Calculate the sum of the values

\[
\text{Sum} = 6 + 2 + 3 + 4 + 10 = 25
\]

Divide the sum by the number of data points

\[

$$\begin{aligned} &N = 5\\ &\text{Mean} = \frac{25}{5} = 5 \end{aligned}$$

\]
