A manufacturer of flea collars for animals that weigh less than 5 kilograms injects the collars with 15 milligrams of a biocide that only acts on fleas. The manufacturer will release a collar that has no less than 14 milligrams and no more than 16 milligrams of insecticide. The following list shows the result of sampling 36 collars from an actual production run of 720 collars.
17, 14, 14, 16, 14, 15, 15, 15, 16, 14, 16, 14, 15, 15, 15, 16, 13, 13,
13, 13, 13, 14, 14, 13, 17, 14, 15, 13, 14, 15, 16, 17, 14, 17, 14, 15
4. How many flea collars out of a production run of 720 collars would be acceptable to ship according to this sample?
5. How many flea collars out of a production run of 720 flea collars would have too much biocide and could not be shipped? Explain your reasoning.
