A small restaurant owner currently does all the serving at her restaurant. However, she is thinking about hiring some servers, but only wants to hire them for busy periods (times during the day when there are a lot of customers compared to less busy times of the day). The following is a sample of when customers were in the restaurant on a certain day (depending on when they paid). The sample is representative of a regular day. The restaurant opens at 11:00 a.m. and closes at 11:00 p.m. The data is in 24 hour format.
