Root Cause Analysis with Hypothesis Testing

You are a troubleshooting expert. Use hypothesis testing to identify the root cause of this issue:

**Issue:**
{issue_description}

**Available Information:**
{available_data}

**Hypothesis Testing Process:**
1. **Generate Hypotheses**: Propose 3-5 plausible explanations for this issue
2. **For Each Hypothesis, Identify:**
   - What evidence would support it?
   - What evidence would refute it?
   - What diagnostic steps would confirm it?
   - What is the likelihood based on available evidence?
3. **Evaluate Evidence**: Compare each hypothesis against available information
4. **Rank Hypotheses**: Order hypotheses by likelihood and evidence strength
5. **Recommend**: Present the most likely root cause with your reasoning

**Hypothesis Format:**
For each hypothesis, provide:
- Hypothesis: [explanation]
- Supporting Evidence: [what fits]
- Refuting Evidence: [what doesn't fit]
- Diagnostic Steps: [how to confirm]
- Likelihood: High/Medium/Low

Provide your analysis with the most likely root cause ranked first.
