In this scenario, you want to encourage a more organized and efficient approach to handling emails among your team members. The schedule chosen involves checking and responding to emails. Rather than responding to each email as it arrives (continuous reinforcement), you opt for an intermittent schedule. Now, you decide that the team will respond to emails in batches, but the timing is not fixed. It could be after every fifth email, after a variable number of emails, or after a variable amount of time has passed since the last batch response. This way, team members are encouraged to stay on top of their emails, but they can't predict exactly when the next batch response will happen. It adds an element of unpredictability and encourages a balance between promptness and efficiency. Team members might find themselves more focused and ready to tackle a batch of emails, knowing that their effort will be reinforced, but they can't predict the exact moment it will occur. Label this type of schedule (fixed ratio, fixed interval, variable interval, variable ratio) and state the effects this schedule is likely to have on the target behavior
