Step 1: Identify the concept.
Both statements talk about estimating human resource needs, so this question is testing the difference between workload analysis and workforce analysis.
Step 2: Recall the correct definitions.
Workload analysis works out how many people and what type of skills are needed to complete the jobs on hand. Workforce analysis looks at the people already available in the organisation, their number and their skill types.
Step 3: Check each statement.
Statement I describes workforce analysis as telling us how many people are needed, but that is actually the job of workload analysis, so Statement I is false. Statement II says workload analysis tells us how many people are available, but that is the job of workforce analysis, so Statement II is also false since the two terms have been swapped.
Step 4: Conclude.
Final answer: Option 4, both statements are false since the definitions have been interchanged.
