       ●In a Chi-Square analysis, we are 
        assessing if there is a difference 
        between an observed frequency and an 
        expected frequency
       ●If students had no preference for any 
        type of coke, we would expect to see 
        roughly an equal number of 25 students 
        in both observed and expected cells for 
        each favour
