The members of a rock climbing club can use an indoor rock climbing facility anytime they wish as part of their club membership. As it creates a new budget, the club decides to investigate how often the members use the indoor climbing facility. Then it will decide whether to increase the budget for this facility. Manuel and Gretchen are in charge of gathering this information, so they survey the members of the club. Each person will administer the survey to 15 randomly selected members and record how many days in the past month those members used the indoor facility. Their data is shown in the table.
