Question

ch 22 eggs that are contaminated with salmonella can cause food poisoning among consumers. a large egg producer takes an srs of 200 eggs from all the eggs shipped in one day. the laboratory reports that 16 of these eggs had salmonella contamination. unknown to the producer, 0.2% (two - tenths of 1%) of all eggs shipped had salmonella. in this situation
\\( \frac { 16 } { 200 } \\) is a parameter and 0.2% is a statistic.
both 0.2% and \\( \frac { 16 } { 200 } \\) are statistics.
0.2% is a parameter and \\( \frac { 16 } { 200 } \\) is a statistic.
both 0.2% and \\( \frac { 16 } { 200 } \\) are parameters.

Explanation:

A parameter is a characteristic of a population. Here, \(0.2\%\) is about all eggs shipped (the population), so it is a parameter. A statistic is a characteristic of a sample. \(\frac{16}{200}\) is calculated from the sample of 200 eggs, so it is a statistic.

Answer:

\(0.2\%\) is a parameter and \(\frac{16}{200}\) is a statistic.
