Calculating Average Gym Visits

A local gym analyzed the average number of visits per week by its members. The following data shows the distribution of visits for a sample of 100 members:

• 0-1 visits: 10 members
• 2-3 visits: 20 members
• 4-5 visits: 30 members
• 6-7 visits: 25 members
• 8 or more visits: 15 members

To find the average number of visits per week for the sampled group, calculate the weighted average based on the number of members in each category.
