1️⃣ Question 1

Based on the histogram, approximately what percent entered at least 30 competitions?

• ❌ 40

• ❌ 20

• ❌ 10

• ✅ 80

Explanation:
Counts for bins ≥30: 30–31 (10) + 32–33 (8) + 34–35 (10) + 36–37 (9) + 38–39 (3) = 40 out of 50 total → 40/50 = 80%.

• ✅ The mean

• ❌ The median

• ❌ They are the same

• ❌ Can’t tell

3️⃣ Question 3

Which day has the largest third quartile (Q3)?

• ❌ Monday

4️⃣ Question 4

Which day has the largest IQR (most spread in the middle 50%)?

• ❌ Monday

• ❌ Wednesday

• ✅ Friday

• ❌ Sunday

• ❌ Can’t tell

Explanation:
IQR = Q3 − Q1: Mon=60−40=20, Wed=250−200=50, Fri=380−150=230, Sun=680−520=160 → Friday has the largest IQR.

• ❌ 25%

• ❌ 10%

• ✅ 0%

Explanation:
Boxplot upper whisker = 1350, which is the maximum (no outliers beyond). Yanis’s 1375 > 1350, so no competitors climbed more → 0%.
