The sampling plan allows for one reject, meaning that if the sample of ten has more than one dirty napkin, the bundle should be returned to the laundry. In this case, the sample of ten contains two dirty napkins, which is greater than the allowable one reject. Therefore, the bundle should be returned to the laundry.
