1. Identify the appropriate control charts to use with each scenario and state WHY.
a. A hospital is trying to improve its image by changing its menu offerings. It offers a questionnaire with each meal served asking about whether the patient is satisfied or not. You have a 100-patient sample of survey results from over the past 14 days capturing the number of unsatisfied patients.
b. Pioneer Chicken provides a "lite" chicken with 30% fewer calories than standard chicken. When the process of "lite" chicken breasts production is in control, the average chicken breast contains 420 calories. Pioneer wants to design a control chart to monitor the caloric content. It plans to choose 5 chicken breasts at random every 2 hours a shift operates for which the caloric content is checked.
c. A school board is trying to evaluate a new math program introduced to second graders in five elementary schools in the county. A sample containing the number of test errors in each school is captured.
