A real estate developer is building a new apartment complex. He wants to know if people have preference for one of 3 different floor plans. He surveyed n = 60 people and asked which floor plan they preferred. The data are below: Floor Plan A Floor Plan B Floor Plan B %3D 20 24 16 19. Calculate the degrees of freedom (df) for chi-square. 20. Using an a = .05, what is the critical value for chi-square (x²crit)? 21. Assuming all choices would be equally likely to be chosen, what would be the expected frequency (f) for all groups?
