Make a chart based on the case below, and draw an inference from the data. Apple Tree Fitness is an independent fitness club in Tokyo located near a private railway line. The club mainly targets women, but recently the number of male members has increased. Business results have been improving every year, although slowly. As the owner, you are concerned that the customers' age may be shifting upwards, based on your observation during a site visit. So far, there does not seem to be much impact on the profit ratio, etc., but if customers are aging, it could impact the business in the long run. Apple Tree Fitness normally asks customers to provide their address and contact details when they became members, but has a policy of not asking for information on their age or marital status. Therefore, to find out their age, the company sent a questionnaire to customers who volunteered, and offered them a small reward for participating. The following are the results of the surveys done both three years ago and this year.
