Answer:
Proportional Stratified Sampling:
Proportional stratified sampling is appropriate when various strata are different in size. For example, imagine a small town that has 1000 Jewish residents, 2000 Catholics and 3000 protestants. A local newspaper publisher a section dealing with interfaith church news religious events, and syndicated articles of interest to the religious community in general. The editor decides to conduct a survey in order to obtain certain information and opinions from the papers readers .
Stratified Random Sampling:
Stratified random sampling has the advantage of guaranteeing equal representation of each of the identified strata. It is most appropriate when the strata are roughly equal in size in the overall population
