A variable measured at the interval or ratio level can have more than one arithmetic mean.
It is a HISTOGRAM.

No, it is a ratio scale.
Four types of intermittent schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Fixed ratio schedules provide reinforcement after a set number of responses, while variable ratio schedules provide reinforcement after a varying number of responses. Fixed interval schedules provide reinforcement after a set time interval, while variable interval schedules provide reinforcement after a varying time interval.
It is ratio.

Case number would be nominal scale; the number has no meaning.
Ratio reinforcement schedules deliver reinforcement based on the number of responses emitted by the individual, while interval reinforcement schedules deliver reinforcement based on the passage of time and the first response after a specified time interval. Ratio schedules tend to generate higher response rates compared to interval schedules.
