Essays / Critical analysis and research methods of a career choice research paper [2]

I am struggling with two separate issues with this specific research paper.

TITLE:

NSW Police Force and the recruitment and application process

DESCRIPTION: A report in the police recruitment process, what it takes to become a police officer and what being a police officer involves.how

I have to use both qualitative and quantitative research for this paper - how can I incorporate quantitative into this paper?

I am unsure of how to efficiently write a critical analysis of a research paper. I fully understand how to do it for a piece of writing, fictional text or something similar, but not for a research paper.

Any help would be amazing.
Thanks in advance
