Now assume the researcher wants to use alpha = .05. Given this alpha--and given the df which you should be able to figure out--what is the correct value for the χ2Critical?

A researcher is testing whether traffic tickets are given out equally to drivers driving different makes of car.  The makes of car that he is including are: Volkswagon, Volvo, Mercedes, Ford, GMC, Chevrolet, and Tesla.  So, the categorical (nominal) variable is make of car, and you should be able to determine c, the number of categories that exist on this variable.  The researcher is doing this study by looking at the make of car for a sample of n=25 traffic tickets.

Now assume the researcher wants to use alpha = .05.  Given this alpha--and given the df which you should be able to figure out--what is the correct value for the χ²_Critical?
