4. Creating and Interpreting a Confidence Interval; Minimum Sample Size In 2013 an environmental group 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 mislabeled according to the US FDA guidelines. Source: usa.oceana.org Include appropriate titles, labels, and units as you answer the questions below. Construct a 95% confidence interval for the proportion of all seafood sold in the US that is mislabeled or misidentified. Round to three decimal places. Interpret your confidence interval. What would be the minimum random sample size needed to be 95% confident with a margin of error of 3%?
