1. A logistics company is developing a marketing strategy to increase its company's Competitive Advantage (CA) that recently has been decreasing. One of the strategies considered to increase the company's CA is through a Green Marketing Implementation strategy. To ensure that this strategy is the right strategy to implement, the Research and Development Division of the company will conduct a study of various logistics companies in Indonesia that have implemented the Green Company Policy. The results of a preliminary study of various literatures have identified several variables that might be included in the framework or research model. These variables include the implementation of green marketing, company compliance with various rules related to sustainability, company perspective in implementing green marketing, company orientation to the environment, company policies, and so on. Of course, as the focus of the company's research, the CA variable itself needs to be considered as the dependent variable. The approach that will be used is through quantitative research.

1. With the variables that have been identified as mentioned above, draw a framework or research model for the research to be carried out.
2. Formulate various research questions related to the research model in item a.
3. Formulate all hypotheses in accordance with the research model in question.
4. What can be used as the population for the target of this research study. What sampling technique is recommended to be used in selecting the sample company respondents?
