Statistics Calculate the arithmetic mean of these 7 numbers: 46, 72, 186, 43, 44, 42, 32... — Step-by-Step Solution

📝 Problem

Calculate the arithmetic mean of these 7 numbers: 46, 72, 186, 43, 44, 42, 32. Verify that the sum is 465.

✨详细解答

1. 📊 Data: {46, 72, 186, 43, 44, 42, 32, 465}, n = 8

2. 🧮 Mean: x̄ = (46 + 72 + 186 + 43 + 44 + 42 + 32 + 465) / 8 = 465/4

3. 📐 Median: Sorted: {32, 42, 43, 44, 46, 72, 186, 465}

Median = 45
