Chi Squared goodness-f-fit test
Use these parameters to guide me through the steps in solving this problem.
The car dealership did a study on 6 different uniform variations. In this study, they had personnel from all companies across the world wear the different uniforms at different times to identify which was most liked. 120 people were asked
