applications of statistical data mining methods
... By assessing the results gained from each stage of the SEMMA process, you can determine how to model new questions raised by the previous results, and thus proceed back to the exploration phase for additional refinement of the data. Effective statistical and graphical data mining tools can enable ag ...

... a) Not correct. A confidence interval is for the mean weight gain of the population of all cows. It says nothing about individual cows. This interpretation also appears to imply that there is something special about the interval that was generated, when this interval is actually one of many that cou ...
