In 2013 the environmental group Oceana (usa. oceana. org) analyzed 1215 samples of seafood purchased across the United States and genetically compared the pieces to
standard gene fragments that can identify the species. Laboratory results indicated that
33% of the seafood was misllabeled according to U. S. Food and Drug Administration
guidelines.
Construct a 95% confidence interval for the proportion of all seafood sold in the United
