B is corrent because systematic sampling is a procedure where a random start is obtained and then every nth item is selected. For example, a sample of forty from a population of a thousand would require selecting every 25th item after obtaining a random start between items 1 through 25. Therefore, although the forms are not consecutively numbered, the use of systematic sampling may be appropriate. A is incorrect because selection of a random sample is possible even though the population is not consecutively numbered. C is incorrect because there is no special reason for using stratified sampling. Stratified sampling breaks down the population into subpopulations and applies different selection methods to each subpopulation. This selection method is used when the population consists of different types of items (e.g., large balances and small balances). D is incorrect because random number tables can be used even though the forms are not consecutively numbered. If random numbers are selected for which there are no forms, they are ignored. This is the same as if there are 86,000 items in a consecutively numbered population and random numbers selected between 86,000 and 99,999 are ignored.
