A team of researchers analyzed the meat from each in a sample of 2727 "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 66 of the 2727 fillets (or 2222%) were not red snapper but the cheaper look-alike variety of fish. 1. Identify the parameter of interest to the researchers.
2. Explain why a large-sample confidence interval is inappropriate to apply in this study.
A. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is less than 15.
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 15.
C. It is inappropriate because the expected probability of success is 0.23.
D. It is inappropriate because the sampling distribution is approximately normal.
3. Construct a 90% confidence interval for the parameter of interest using Wilson?s adjustment. The 90% confidence interval is
4. Give a practical interpretation of the confidence interval.
