Stats: Review Chapter 11 - Sampling Distributions

People who eat eggs that are contaminated with salmonella can get food poisoning. A large egg producer randomly selects 200 eggs from all the eggs shipped in one day. The laboratory reports that 9/200 = 0.045 of these eggs had salmonella contamination. Identify the POPULATION, the parameter, the sample, and the statistic.

• 200 eggs that are randomly selected per day

• all eggs shipped in one day

• proportion of eggs shipped that are contaminated with salmonella

• proportion, 0.045, of eggs sampled that are contaminated with salmonella
