The assignment brief suggest a single aim so you will have to condense these.
You are expected to gather a set of data and undertake basic analysis of it you dont seem to have done this see below:
5. Gather a substantial data set that relates to your research problem. Describe the data using text and the measures (of central tendency and dispersion) and visualisations you consider best suitable.
6. Propose a model for the data collected and perform a type of statistical analysis that suits the model. By model, I refer to any sort of statistical representation either to describe the data and gain insights from it, or to study relationships between different variables.
