Average Attendance Comparison in Fitness Classes

A fitness center tracks the number of members who attend specific workout classes over a month. The following data represents the attendance for three classes during the first week:

• Yoga: 20 attendees
• Pilates: 15 attendees
• Spin: 25 attendees

At the end of the month, the center wants to analyze the average attendance for each class over the four weeks of that month. If we denote the average attendance for Yoga as $A_Y$, Pilates as $A_P$, and Spin as $A_S$, what can we infer about the relationship between these averages?
