the median

A concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The following data represent the strength of nine randomly selected casts (in psi). 3950, 4080, 3100, 3000, 2950, 3840, 4080, 4030, 3730 Compute the median strength of the concrete (in psi). The median strength of the concrete is 4 psi of pressure
