Determine whether the following sampling is dependent or independent. Indicate whether the response variable is qualitative or q

NeTakaya

Answer:

1. option D

2. option A

Step-by-step explanation:

Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.

The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
