Note: Cluster sampling is not as accurate as simple or stratified random sampling.
Weighted Shortest Job First gives preference to jobs with characteristics such as, first, the size of the project (smaller is better) Second, the value of the project (higher is better).
In order to determine a relative ranking, Weighted Shortest Job First (WSJF) uses a technique for assigning a weight, or value, to each job, and then by dividing that by the length of the job. It also gives preference to jobs with characteristics such as the size and value for a project.
Weighted Shortest Job First is a prioritization model used to sequence jobs eg., capabilities, features, and epics in order to produce maximum economic benefit.

From the viewpoint of price, and given that consumers always prefer to spend less in instances where two goods are substitutes, it then means that Kindle can be used and preferred in place of Nooks given that the price of Nooks had gone up. Therefore, increasing the price of Nooks causes a corresponding increase in the demand for Kindles.
