The output of an extrusion process is known to have a 10% defect rate. A Six Sigma Black Belt recently made changes to the extrusion process as the result of some process analysis that was completed. 567 extrusions were collected after the changes were made and 40 were identified as defectives. Were the changes effective?

we conclude that the proportion of defects is less than 10%
therefore we conclude that the changes were effective
