Answer:
114
Step-by-step explanation:
Given that
THe data that was collected over a 40 years  is  112, 98, 139, 142, 120, 110, 114, 123, 137, 114, 92, 140, 109, 133​
We need to find out the mode
As we know that
The mode is the value that is highly repeated
So according to the data, 114 would be repeated two times
So this represent the mode of the data
