Simple random sample
Answer each question individually.
a. What is a simple random sample?
b. When the Bureau of Labor Statistics conducts a survey, it begins by partitioning the U.S. adult population into 2007 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? If it is not a simple random sample, what type of sample is it?
c. Refer to the primary sampling units described in part (b) and describe a sampling plan that results in a simple random sample.
If you randomly select one adult from each primary sampling unit, is the result a simple random sample? Why or why not?
