9.70 Increased Yield An agronomist has shown experimentally that a new irrigation/fertilization regimen produces an increase of 17,635 cm per quadrant (significant at the 1% level) when compared with the regimen currently in use. The cost of implementing and using the new regimen will not be a factor if the increase in yield exceeds 26,453 cm per quadrant. Is statistical significance the same as practical importance in this situation? Explain.
