Statistics Calculate the arithmetic mean of these 10 numbers: 88, 154, 88, 133, 129, 25,... — Step-by-Step Solution

📝 Problem

Calculate the arithmetic mean of these 10 numbers: 88, 154, 88, 133, 129, 25, 71, 184, 97, 158. Verify that the sum is 1127.

✨Detailed Solution

1. 📊 Data: {88, 154, 88, 133, 129, 25, 71, 184, 97, 158, 1127}, n = 11

2. 🧮 Mean: x̄ = (88 + 154 + 88 + 133 + 129 + 25 + 71 + 184 + 97 + 158 + 1127) / 11 = 2254/11

3. 📐 Median: Sorted: {25, 71, 88, 88, 97, 129, 133, 154, 158, 184, 1127}

Median = 129
