f.
If there were a Type I or Type Il error given this sample, what would it be, and what would
the implications of that be?
2. In the December 2002 issue of Consumer Reports, Consumers Union reported on their
investigation of the presence of bacteria in packages of chicken sold in supermarkets. They
randomly selected both name brand (Perdue) and store-brand chicken in several different U.S.
cities. Laboratory tests found campylobacter contamination in 25 of the 75 Perdue packages,
and in 37 of the 75 store brand packages. Does this indicate that shoppers would be safer
buying the name-brand product? Use a 5% level of significance.
a. State the null and alternative hypotheses
Ho:
b. What calculator test will you use? List the requirements that must be met to use this test,
and indicate whether the conditions are met in this problem.
c. Run the calculator test and obtain the P-value.
d. Based on your P-value, will you reject or fail to reject the null hypothesis?
e. Interpret your conclusion from part d in the context of this problem.
