Use the following weights in pounds of a sample of high school football players.
X = {181, 206, 168, 163, 162, 184, 253, 162, 166, 165, 168, 150, 195, 200, 225, 166, 174, 166, 186, 178, 250, 241, 212, 171, 190, 260, 172, 183, 169, 174}.
1. Mean 2. Median 3. Mode 4. range 5. Variance 6. Standard deviation 7. Midrange 8. MAD
9. Σ(x-xbar) 10.Σx 11. Σ(x^2) 12.(Σx)^2 13. Σ(x-xbar)^2
14. Use Chebysheff's Theorem to find at least what % of the weights are within xbar ± 3.5s
