Determine if each of the following is a random sample. Explain your answer. Twelve jurors chosen through examination by opposing lawyers.

No, this is not a random sample. The jurors were not chosen randomly but rather selected through a specific process.

No, choosing twelve jurors through examination by opposing lawyers is not a random sample. A random sample is one where each unit or individual in the population has an equal chance of being selected. In the case of selecting jurors through examination by opposing lawyers, it is not a random process as lawyers have specific criteria and biases when selecting jurors that align with their case strategy. This method of selection introduces a level of subjectivity and potential bias, making it a non-random sample.
