an agronomist has shown experimentally that a new irrigation/fertillization regimen produces an increase of 2 bushels per quadrat(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 3 bushels per quadrat. is statistical significance the same as practical importance in this situation? explain Solution No, statistical significance is same as practical importance in this situation,because the incresase of 2 bushels per quadrant is shown experimentally but the increase of 3 bushels per quadrant in yield is said statistically.
