- ALower (0.76 vs 0.8)
- BHigher (0.84 vs 0.8)
- CSame (0.8 vs 0.8)
- DLower (0.70 vs 0.8)
Step-by-Step Solution
Day 1 P = 24/30 = 0.8. Pooled = (24+14)/(30+20) = 38/50 = 0.76, which is lower than 0.8.
Answer: A) Lower (0.76 vs 0.8)
A footballer took penalties on two days.
Day 1: 30 attempts, 24 scored. Day 2: 20 attempts, 14 scored.
