Essay

The ZZZ chain of motels has a standard method of constructing their buildings to
maximize the ease of parking for its customers. The rooms are arranged in adjacent
buildings, A and B, so that customers can park close to their rooms. The layout for
the 48-room motels is diagrammed below: $$\begin{array}{l}\text {Route 66}\\\text {Building A}\\\begin{array} { | l | l | l | l | l | l | l | l | l | l | l | l | } \hline & & & & & & & & & & & \\\hline & & & & & & & & & & & \\\hline\end{array}\end{array}$$
$$\begin{array}{l}\text {Building B}\\\begin{array} { | l | l | l | l | l | l | l | l | l | l | l | l | } \hline & & & & & & & & & & & \\\hline & & & & & & & & & & & \\\hline\end{array}\end{array}$$ The manager wishes to assess customer satisfaction with the motel services. His plan
is to survey the adults in each of 12 rooms. The cleaning staff will place surveys on
the customers' beds before they check in to the motel. As she tries to decide on an
appropriate sampling strategy, the manager realizes the rooms in Building A might be
noisier than Building B, and this should be taken into account.
a) What sampling strategy should she use in this situation? Provide appropriate
statistical justification.
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.
