The group purchased 259 pieces of seafood from various kinds of food stores and restaurants in the three states and genetically compared the pieces to standard gene fragments that can identify the species. The study found that 13 of the 24 "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. a) Are the conditions for creating a confidence interval satisfied? Explain.

Sample proportion p = 13/24 = 0.541667

Conditions for creating confidence interval:
