How could I answer all parts to this question please?

I am re-asking this question and this is an example question provided by my professor in preparation for an upcoming examination next month. It is not something I can submit as a piece of work. If you can answer the questions and provide me with explanations that I can use to study from, I would highly appreciate it. Thank you.

Q2: Distance from birthplace [15 marks] Each term we ask students in ENV5278 to use an online calculator to estimate the distance between Waterloo, Ontario and their city of birth. The results show a large peak at distances below 500 km (most of Ontario], and a wide range of longer distances up to 16,000 km (Fig. 2]. The University is interested in the extent to which the COVID-19 pandemic has changed the demographics of its undergraduate students, so it is natural to ask whether distance from place of birth has changed between 2021 and 2019 (the last time the survey was conducted pre- pandemic]. Frequency 40 60 BO 1 00 20 Distance (km) Figure 2: Histogram of distance from birthplace reported by ENVSZ78 students in Fall 2021 {grey shaded bars} and Fall 2019 (red unlled bars]. a) Write appropriate null and alternative hypotheses for this question.

Provide a one- sentence interpretation of this information. [2 marks] e) The figure below, generated by SPSS, shows a histogram of distance from birthplace for each term (F19 and F21).
