Question

A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property. The manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view. What type of sample was obtained

Answer 1

The hotel manager used a stratified simple random sampling method by selecting random samples from two distinct strata: rooms with water views and rooms with golf course views.

Step-by-step explanation:

A stratified sample was obtained.

A stratified sample is a sample in which the population is divided into strata, or subgroups, and then a sample is drawn from each stratum. This type of sample is used when the population is not homogeneous, or when the researcher wants to ensure that the sample is representative of the population in terms of some important characteristic.

In this case, the population of rooms is not homogeneous, because the rooms on one side of the hotel have a water view, while the rooms on the other side have a golf course view. The manager wants to ensure that the sample is representative of both types of rooms, so he selects an SRS of rooms from each stratum.
