To calculate the mean of the times it took to complete the obstacle course, you need to first sum up all the times and then divide by the number of tests.
The times from the dot plot you provided are: 5, 6, and 10 minutes.
**Step 1: Sum the times:**
\[ 5 + 6 + 10 = 21 \text{ minutes} \]
**Step 2: Count the number of tests:**
There are 3 times recorded.
**Step 3: Calculate the mean:**
\[ \text{Mean} = \frac{\text{Total time}}{\text{Number of tests}} = \frac{21}{3} = 7 \text{ minutes} \]
Therefore, the mean time to complete the obstacle course is **7 minutes**.
