Research Topic : Are accidents caused by maintenance-related problems distributed differently from incidents in the entire aviation sector

Variables

1. Accidents Caused by Maintenance-Related Problems (ACM): This is the independent variable since it is the element that researchers want to change or test to see how it affects other factors.
2. Incidents in the aviation sector (IAS) : This additional independent variable represents all aviation-related incidents, regardless of their origin.
3. Distribution (D): This is the dependent variable because it is reliant on the occurrences or degrees of both ACM and IAS. It represents the distribution of these occurrences or accidents among the aviation industry.

For above research topic and variables

1. State the null and alternate hypotheses.
2. Describe which quantitative methods could be used to address your research question(s). Describe any that could be applied.
3. Explain which would be the most appropriate and why.
4. Explain the advantages and disadvantages of the method you select.
