(b) The sampling plans in this set differ in their efficiency options and sampling frequency.
(c) For period-based sampling plans, the number of sampling plans in this set varies with the efficiency options that your input data allow. It ranges from 6 sampling plans if you do not consider the PPMT and grouping options to 18 sampling plans if you consider them.
(d) For interval-based sampling plans, the number of sampling plans in this set varies with your weekly service patterns. It ranges from 8 sampling plans if you operate your service 5 days a week to 12 sampling plans if you operate 7 days a week.
(e) The set of sampling plans changes when you change your input data.
