A team of researchers analyzed the meat from each in a sample of 17 "red snapper" fish fillets purchased from vendors across a region in an effort to estimate the true proportion of fillets that are really red snapper DNA tests revealed that 13 of the 17 fillets (or 76%) were not red snapper but a cheaper look alike variety of fish. Complete parts a through c. a. The parameter "x" is the true proportion of fish fillets that are actually red snapper. O True O False b. Explain why it is not appropriate to use a confidence interval in this study. Choose the correct answer below O A. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is less than 5. O B. 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 5 O C. It is inappropriate because the expected probability of success is 0.76 O D. It is inappropriate because the sampling distribution is approximately normal. C. The population (true) proportion of fish fillets that are actually red snapper is . (Use 2 decimal places rounded.)
