• Fundamental Research (Pure / Basic Research):
• Fundamental Research is investigation undertaken primarily to expand the frontiers of scientific knowledge, formulate fundamental theories, or uncover universal natural laws without any immediate commercial objective or practical problem-solving application in mind.
• Distractors:
• Exploratory Research: Initial research conducted to clarify the nature of ambiguous, poorly understood problems.
• Action Research: Immediate, localized problem-solving research conducted by practitioners to solve real-time organizational issues.
• Explanatory (Causal) Research: Focuses on explaining why phenomena occur by identifying specific cause-and-effect relationships.

Correct option: (1) Fundamental research

• Sequential Steps in Cost-Benefit Analysis:
• The standard four-stage sequence in performing CBA for project management is:

• Identification: Identifying all tangible and intangible economic costs and benefits associated with the project over its lifecycle.
• Quantification: Measuring and assigning monetary valuation to the identified physical inputs and outputs.
• Comparison: Discounting future costs and benefits to present value to compare streams using metrics like NPV, BCR, and IRR.
• Decision: Accepting, rejecting, or prioritizing projects based on established decision rules (e.g., $NPV \gt 0$, $BCR \gt 1$).
  • Correct Sequence: (A), (D), (C), (B), corresponding to Option 2.

• Decision Rule in Hypothesis Testing:
• In statistical hypothesis testing using critical values:
• We calculate a test statistic (e.g., $Z_{\text{cal}}$, $t_{\text{cal}}$, $F_{\text{cal}}$) and compare it against the tabulated Critical Value ($Z_{\alpha}$).
• Rejection Rule: If the calculated test value falls into the rejection region (exceeds the critical threshold, i.e., $|\text{Test Value}| \gt \text{Critical Value}$, meaning Critical Value is less than Test Value), we reject the Null Hypothesis ($H_0$) at that significance level.
• Conclusion: Option 1 (less, rejection) correctly identifies the rejection condition.

Correct option: (1) less, rejection
