Customers respond to a single question indicating on a Yes/No scale whether they were satisfied or dissatisfied with their golf rounds. The data provided below (and provided in an Excel file: 2022 M7 Quality Management Problem 5.xlsx) gives the number of dissatisfied customers noted in 150 responses each week over 12 weeks.
