This proposal is a continuation of a paper I have been working with writer 64813. From previous discussions, these are the sections I need completed: 1. Complete section “advancement of scientific knowledge”. 2. Since reliability and validity cannot yet be completed, and the sample size was filled with available information, complete the introduction section (definitions, advancement of scientific knowledge, summary, and assumptions, limitations and delimitations), and methodology (introduction, limitations and delimitations, and summary). Add needed points to the literature review and make any relevant changes inside the text if needed.
