Mislabeled Fish. Researchers with Oceana, a group dedicated to preserving the ocean ecosystem, reported finding that 33% of fish sold in retail outlets, grocery stores, and sushi bars throughout the United States had been mislabeled (San Francisco Chronicle). Does this mislabeling differ for different species of fish? The following data show the number labeled incorrectly for samples of tuna and mahi mahi. (a) Use the Excel spreadsheet you created to find the 90% confidence interval for the difference in proportion of Tuna and Mahi Mahi that has been mislabele Copy the confidence interval to your homework. (b) Interpret the meaning of your confidence interval in terms of the problem. (Refer back to the exercise in (1) to help)
