Warehouse clubs are retailers that offer lower prices than traditional retailers, but they sell only to customers who have purchased memberships and often merchandise must be purchased in large quantities. A warehouse club may offer more than one type of membership, such as a regular membership R for a low annual fee and an upgraded membership U for a higher annual fee. The upgraded membership has additional benefits that might include extended shopping hours, additional discounts on certain products, or cash back on purchases.
A local warehouse club has determined that 20% of its customer base has the upgraded membership.
In an effort to sell more upgraded memberships, sales associates are placed at the entrance to the store to explain the benefits of the upgraded membership to customers as they enter. Suppose that in a given time period five customers enter the store.
