hypotheses, and recommend solutions.

Framework Development: Create a structured approach to analyze the problem. - Data
Analysis: Interpret charts, tables, and exhibits provided. - Hypothesis Testing: Formulate
and test hypotheses based on data. - Recommendation & Summary: Summarize findings
and suggest actionable steps.

do it efficiently and confidently. Recognizing common pitfalls helps you develop strategies
to avoid them.
