Overview Of The Assignment

This assignment will test your skills of collecting and analysing data to answer a specific business problem. It also gives you the opportunity to apply the theories you have learned in this course such as finding numerical summaries, displaying with appropriate graphs and using statistical inferences to solve business problems, including constructing hypotheses, test them and interpret the findings. You may have to use two Data sets. One Data set will be sent you via KOI student email individually and other you need to find or collect.

Suppose you are working for an agency who analyses airlines services Data of Australia to make a recommendation to improve Airport services to airline. You will be given series of research questions. Use your knowledge that you gain from this course to answer these questions by displaying appropriate outputs of Excel, StatKey or Wolfram alpha.
