sampling units described in part c. Refer to the primary b and describe a sampling plan that results in a simple random sample b. When the Bureau of Labor Statistics conducts a survey, it begins by partitioning the United States adult popula- tion into 2,007 groups called primary sampling units Assume that these primary sampling units all contain the same number of adults. If you randomly select one adult from each primary sampling unit, is the result a simple random sample? Why or why not?

Since the population was first divided into groups and the sampling was done afterwards, it was not an example of simple random sampling as it is not possible to select more than one adult from each group which would have been possible in simple random sampling.

Also, If simple random sampling is to be done, then each adult should have equal probability of being selected and should be independent of others. The 2007 adults should be selected without regard to the groups i.e 2007 adults should be chosen from the groups with no restrictions on the number chosen from each group.

Since the population is first divided into various groups and the sampling was done later.

It is not the example of a simple random sampling as it does not allow for selecting more than 1 adult from each group that would have been possible in all simple random sampling.

The 2,007 adults should be selected without regard to the groups The groups are selected with no restrictions on the number chosen from every group.
