Houston North Hospital is trying to improve its image
by providing a positive experience for its patients and their relatives. Part of the “image†program involves providing tasty, inviting patient meals that are also healthful. A questionnaire accompanies each meal served, asking the patient, among other things, whether he or she is satisfied or unsatisfied with the meal. A 100-patient sample of the survey results over the past 7 days yielded the following data:
DAY NO. OF UNSATISFIED SAMPLE SIZE
PATIENTS
1 24 100
2 22 100
3 8 100
4 15 100
5 10 100
6 26 100
7 17 100
Construct a p-chart that plots the percentage of patients unsatisfied
