A consumer advocacy group published a study of labeling of seafood sold in three U.S. states. The study found that 10 of the 20 "red snapper" packages tested were a different kind of fish. Assume that the study used a simple random sample. Complete parts a through c below. are at least 10 "successes" and 10 "failures." D. No, because the sample is a simple random sample, the sample is less than 10% of the population, and there are at least 10 "successes" and 10 "failures." .... b) Construct a 95% confidence interval for the proportion of "red snapper" packages that were a different kind of fish. (0.281,0.719) (Round to three decimal places as needed.) c) Explain what the confidence interval from part (b) says about "red snapper" sold in these three states. Select the correct choice below and fill in the answer boxes within your choice. (Round to one decimal place as needed.) OA.

Transcribed Image Text:A consumer advocacy group published a study of labeling of seafood sold in three U.S. states. The study found that 10
of the 20 "red snapper" packages tested were a different kind of fish. Assume that the study used a simple random
sample. Complete parts a through c below.
are at least 10 "successes" and 10 "failures."
OD. No, because the sample is a simple random sample, the sample is less than 10% of the population, and there
are at least 10 "successes" and 10 "failures."
...
b) Construct a 95% confidence interval for the proportion of "red snapper" packages that were a different kind of fish.
(0.281,0.719)
(Round to three decimal places as needed.)
ain what the confidence interval from part (b) says about "red snapper" sold in these three states. Select the
correct choice below and fill in the answer boxes within your choice.
(Round to one decimal place as needed.)
A. Ninety-five percent of the time, the true proportion of "red snapper" sold in these three states that is falsely
labeled is between % and %.
OB. There is a 95% chance that the probability of any given "red snapper" sold in these three states being actual
red snapper is between % and %.
OC. One is 95% confident that between
states was not actually red snapper.
OD. One is 95% confident that between % and
these three states is not actually red snapper.
