Verified step by step guidance

1. Understand the concept of reinforcement schedules in operant conditioning, which are rules that dictate how and when a response will be followed by a reinforcer.
2. Identify the four main types of reinforcement schedules: fixed ratio, variable ratio, fixed interval, and variable interval.
3. Recognize that a fixed ratio schedule provides reinforcement after a set number of responses. In this case, Tammy receives reinforcement (a dollar for her troop) after selling a fixed number of boxes (25).
4. Differentiate between fixed ratio and other schedules: Fixed interval involves reinforcement after a set time period, variable ratio involves reinforcement after a varying number of responses, and variable interval involves reinforcement after varying time intervals.
5. Conclude that Tammy's situation aligns with a fixed ratio schedule because the reinforcement (dollar for the troop) is contingent upon a fixed number of responses (selling 25 boxes).
