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 Patients Sample Size
1 22 100
2 22 100
3 10 100
4 17 100
5 10 100
6 26 100
7 15 100
Control limits to include 99.73% of the random variation in meal satisfaction are:
UCLp = (enter your response as a number between 0 and 1, round to three decimals)
LCL = (enter your response as a number between 0 and 1, round to three decimals)
