Answer:
Quantitative discrete data.
Step-by-step explanation:
We have been given a data for the number of machines in five gyms. One gym has 12 machines, one gym has 15 machines, one gym has ten machines, one gym has 22 machines, and the other gym has 20 machines. We are asked to determine the type of the data.
We can see that our given data represents quantity of machines, so our data will be a quantitative data.
Since each gym has a specific number of machines, so our data is discrete and it is not continuous.
Therefore, our given data is a quantitative discrete data.
