Answer:
The median is 2.65 seconds
Step-by-step explanation:
So the median is the middle number. First of all, we have to sort them into ascending order.
2.35, 2.38, 2.43, 2.65, 2.69, 2.78, 10,91.
Since this is median and not mean, we don't need to get rid of outliers / anomalies.
The middle number in that would be 2.65.
