Mislabelled seafood In December 2011, ConsumerReports published their study of labelling of seafoodsold in New York, New Jersey, and Connecticut. Theypurchased 190 pieces of seafood from various kinds offood stores and restaurants in the three states and geneti-cally compared the pieces to standard gene fragmentsthat can identify the species. Laboratory results indicatedthat 22% of these packages of seafood were mislabelled,incompletely labelled, or misidentified by store or res-taurant employees.a) Construct a 95% confidence interval for the propor-tion of all seafood packages in those three states thatare mislabelled or misidentified.b) Explain what your confidence interval says about sea-food sold in these three states,
