The iCycle Club is organizing a recycling campaign in a neighbourhood. They setup one-stop recycling collection centre around the neighbourhood and would like to study their usage rate. Which of the following is a valid assumption about how many people would make use of the one- stop centre?
It is assumed that 100% of the people near the one-stop center would use it.
It is assumed that none of the people near the one-stop center would use it.
It is assumed that 20% of the people near the one-stop center would use it based on a previous research study.
It is assumed that 90% of the people near the one-stop center would use it as their house is within 0.5 km from the one-stop centers.
Which of the following is the importance of model assessment?

It helps to analyse the accuracy of the results predicted by the model.
It helps to identify the strengths and weaknesses of the built model and understand at a deeper level the behaviour of the model.
It helps to define the proper variables to be used in developing the model.
