How can Ijustify the alignment of my hypotheses to a quasi-experimental research design, my problem and purpose statements, and research questions?

Research Problem Statement

The problem is that fifty percent of standardized test scores in core subject areas declined in an urban school district for students in Grades 7 through 12 due to the Covid-19 pandemic.

Research Purpose Statement

The purpose of this quantitative study is toinvestigate the pandemic's impact on learning and the significant risk to student achievement on standardized tests in core subject areas
