To identify: Whether the sampling is dependent or independent.
Answer to Problem 1RE
Solution: The sampling method used in the given problem is dependent.
Explanation of Solution
Given: There are 20 individuals who are selected randomly for collecting the data.
Explanation: The sample is said to be a dependent sample if the same sample is used for collecting the data for the analysis.
Therefore, it can be concluded that the sampling method used in the given problem is dependent because the data on the “for-profit hospital” and the “not-for-profit hospital” is collected using the same sample.
