Suppose that you have been hired as a summer intern at a large amusement park. Every day, your task is to conduct 200 exit interviews in the parking lot when customers leave. You need to construct questions to address the cleanliness of the park and the customers' intent to return. When you begin to construct a short questionnaire, you remember the control charts you learned in a statistics course, and you decide to write questions that will provide you with data to graph on control charts. After collecting data for 30 days, you plan to construct the control charts.
