Question

A manufacturer of yogurt products stamps a sell date on every container. Yogurt not sold by this date is discarded. As a check on this dating system, 50 containers are kept for 8 days beyond the sell date, the maximum length of time the yogurt should be kept in a home refrigerator. Under such severe conditions, the manufacturer is willing to concede that 10% of the containers will have deteriorated quality. A higher percentage indicates a need for a change in sell-date policy. Assume that 9 of the 50 containers show deteriorated quality. What can you conclude at 3% SL?
