Riverdale Hospital is concerned over the number of times
patients must wait more than 30 minutes beyond their scheduled
appointments. The quality team decided to take random samples of 75
patients to see how many in each sample had to wait more than 30
minutes. Each instance is considered a defect in the clinic
process. The table below contains the data for 15 samples.
