Answer:
67,757 errors per million opportunities
Step-by-step explanation:
Assuming that each customer can only make a single complaint (1 error opportunity per customer), the number of errors per million opportunities (EPMO) is given by:
[tex]EPMO = \frac{complaints}{guests}*1,000,000 \\EPMO = \frac{29}{428}*1,000,000 \\EPMO = 67,757[/tex]
Refington hotel should expect 67,757 complaints per million guests.
