QUESTION: (6 points) The "churn" rate in a subscription business is that rate at which subscribers leave in a given time period. In the US wireless industry, the churn rate is on the order of 10% annually - out of 100 customers at the beginning of a 12 month period, only 90 will be left at the end of the 12 month period.
- Describe several different "boxes" that would represent this 10% churn rate, if you are interested in the sampling variability in a sample of size 250.
-
What resampling process makes these different boxes functionally equivalent?
___ sampling with replacement
___ sampling without replacement - Describe the resampling steps you would take to assess the sampling variability of samples of size 250.
- Describe the resampling steps you would take to assess the sampling variability of samples of size 50.
Note: The answers above can be in the form describing the steps in a box model, such as - put slips of paper in a box - take a sample - etc. (only more detailed).
