In Rocky Mountain National Park, many mature pine trees along Highway 34 are dying due to infestation by pine beetles. Scientists would like to use a sample of size 200 to estimate the proportion of the approximately 5000 pine trees along the highway that have been infested. It is not practical to use an SRS in this setting. A possible alternative would be to use the first 200 pine trees along the highway as you enter the park. Why isn't this a good idea?

Respuesta :

Answer:

then no one would be able to actually see the highway and take in the view

Explanation:

The given alternate possible way given in the question is not good as the sample does not follow the conditions of the definition of SRS in the study.

SRS is a group or sample size of "n" objects in a population of "n" objects in which all the possible samples would have equal chances to occur or happen.

In the alternate case, There 200 trees sample is taken from near the highway, that can have fewer chances to be infected or can have more infected.

  • The fact that the sample was not taken randomly and has not been selected in such a way that each tree has equal chances to happen.
  • The SRS is not possible to obtain as it does not follow the term and conditions of SRS.
  • It creates a bias in the study.
