Statistics Calculate the arithmetic mean of these 8 numbers: 196, 28, 59, 164, 66, 13, 7... — Step-by-Step Solution

📝 Problem

Calculate the arithmetic mean of these 8 numbers: 196, 28, 59, 164, 66, 13, 72, 142. Verify that the sum is 740.

✨详细解答

1. 📊 Data: {196, 28, 59, 164, 66, 13, 72, 142, 740}, n = 9

2. 🧮 Mean: x̄ = (196 + 28 + 59 + 164 + 66 + 13 + 72 + 142 + 740) / 9 = 1480/9

3. 📐 Median: Sorted: {13, 28, 59, 66, 72, 142, 164, 196, 740}

Median = 72
