Of 565 samples of seafood purchased from various kinds of foodstores in different regions of a country and genetically comparedto standard gene fragments that can identify the species, 36% weremislabeled.
a) Construct a 95% confidence interval for the proportion ofall seafood sold in the country that is mislabeled ormisidentified.
b) Explain what your confidence interval says about seafoodsold in the country.
c) A government spokesperson claimed that the sample size wastoo small, relative to the billions of pieces of seafood sold eachyear, to generalize. Is this criticism valid?
a) What is the 95% confidence interval?
The 95% confidence interval is from ___% to ___%.
(Round to one decimal place as needed.)
Part 2
b) What does the confidence interval say about seafood sold inthe country?
A.There is a 95% chance that the true proportion of mislabeledseafood is in the interval.
B.We are 95% confident that the interval captures the trueproportion of all seafood sold in the country that ismislabeled.
C.In 95% of samples of seafood sold in the country, theproportion that is mislabeled will be in the interval.
Part 3
c) Is the government spokesperson's criticism valid?
A.No, until another study produces a different interval,the results should be generalized.
B. No, as long as the necessary assumptions and conditions weremet, the results can be generalized.
C.Yes, the sample size must be at least 10% of thepopulation, or the results cannot be generalized.
