The figure below shows the continuous uniform distribution of customer waiting times at a coffee shop. Determine the mean and standard deviation for the distribution of the waiting times.

$\mu =5.0\text{ min}$

$\sigma =8.7\text{ min}$

$\mu =5.0\text{ min}$

$\sigma =2.9\text{ min}$

$\mu =8.7\text{ min}$

$\sigma =2.9\text{ min}$

$\mu =2.9\text{ min}$

$\sigma =8.7\text{ min}$
