O = Homework: Homework Assignment 10 Question 13, 6.4.57 Part 3 of 4 HW Score: 91.17%, 182.34 of 200 points Points: 4.29 of 10 Save A team of researchers analyzed the meat from each in a sample of 20 "red snapper" fish fillets purchased from vendors across a region in an effort estimate the true proportion of fillets that are really red snapper. DNA tests revealed that 5 of the 20 fillets (or 25%) were not red snapper but the cheaper look-alike variety of fish. Complete parts a through d. a. Identify the parameter of interest to the researchers. The parameter of interest is p, the true proportion of fish fillets that are actually red snapper. b. Explain why a large-sample confidence interval is inappropriate to apply in this study. Choose the correct answer below. O A. It is inappropriate because the expected probability of success is 0.25. OB. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is greater than or equal to 15. C. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is less than 15. OD. It is inappropriate because the sampling distribution is approximately normal. c. Construct a 95% confidence interval for the parameter of interest using Wilson's adjustment. The 95% confidence interval is OD. (Round to three decimal places as needed.)
