I read that I can use the hypothesis testing technique for proportions to decide whether the number of levels for a design variable could be reduced. In literature the following typical test was used:
Ho: pi=0
Ha: pi [itex]\neq[/itex]0 where pi is the proportion of class i (level i ) within the
designated design variable.
For my example I have a set of values 546,464,321,112,123 each representing one level.
Can you please explain how to use the test because I am not clear on that and how to decide about confidence levels
PLease help
