medium📝 Predict Output Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Recall mean formula for uniform distribution
Mean = loc + scale / 2.Step 2: Calculate mean with loc=3 and scale=7
Mean = 3 + 7/2 = 3 + 3.5 = 6.5.Final Answer:
6.5 -> Option CQuick Check:
Mean = loc + scale/2 = 6.5 [OK]
Quick Trick: Mean = loc plus half scale [OK]
Common Mistakes:
MISTAKES- Using loc or scale alone as mean
- Adding loc and scale instead of half scale
- Confusing mean with median
