The sampling is dependent because an individual selected for one sample does dictate which individual is to be in the second sample. O B. The sampling is independent because an individual selected for one sample does not dictate which individual is to be in the second sample. O C. The sampling is independent because an individual selected for one sample does dictate which individual is to be in the second sample D. The sampling is dependent because an individual selected for one sample does not dictate which individual is to be in the second sample Indicate whether the response variable is qualitative or quantitative ( A.
