The strength of concrete is measured by pouring the mix into casting cylinders 6 inches in diameter and 12 inch. tall. The concrete is allowed to set for 28 days. The concrete's strength is then measured. The following data represent the strength of nine randomly selected casts (in psi).
Compute the mean, median, and mode strength of the concrete (in psi).
