A company wants to get feedback on their product and uses a voluntary survey to ask their customers. For example, we can imagine that the company runs a webservice and customers use a web-browser or app to use this service. The link to the survey is placed on the webpage and inside the app, but customers are not required to fill in the survey at any point of using the product. As part of the survey, the customers are asked to rate their satisfaction with the product on a scale of 1 (very satisfied) to 6 (not satisfied). To present the findings of the feedback to the management, the feedback should be mapped to a simple visualization such as a traffic light whether the customers are happy, or action is required. Discuss which bias(es) may arise due to the setup of the way the feedback is acquired and outline potential paths to mitigate them. How is the "traffic light" indicator for the management affected if the probability of taking the survey depends on the satisfaction? Create a numerical simulation to illustrate the result. For simplicity, assume that we can model the results of the survey using a Poisson distribution where we map any value greater than 6 to 6 (not satisfied)
