The ZZZ chain of motels has a standard method of constructing their buildings to

The manager wishes to assess customer satisfaction with the motel services. His plan

the customers' beds before they check in to the motel. In order to make the directions
easy for the cleaning staff to follow, he elects to use systematic sampling.
a) Describe carefully how you would use random numbers to set up the systematic
sampling process. (In your description you may assume you have a random
number table, but do NOT carry out the procedure you describe.)
b) Write a short paragraph for the cleaning staff that explains how to carry out your
method in part (a). The members of the cleaning staff have not taken statistics, so
the use of statistical terminology will not be helpful.
