Question 10 options: True False A high standard deviation means that the data observations tend to be very close to the mean, while a low standard deviation indicates that the data are spread out over a large range of values. Supply Chain Management C Predictive mining tasks perform induction on the current data in order to make prediction. Question 15 options: True Question 11 options: True False Knowledge mining is the process of discovering interesting patterns and knowledge from a large amounts of data. False Question 16 options: True In ---, the database or data warehouse system is fully integrated as part of the data mining system and thereby provides optimized data mining query processing. Thus, the data mining subsystem is treated as one functional component of an information system.
