Explanation Consider two years that are not consecutive from which to collect data. That is choosing the current academic year for Year 2 and the academic year four years earlier for Year 1. Suppose the 2015 for year 1 and 2019 for year 2. The following table represents the number of students enrolled in each classification is given below, 2015 Number of Freshmen Enrolled 15 Number of Sophomores Enrolled 18 Number of Juniors Enrolled 21 Number of Seniors Enrolled 73 Total 127 The formula for calculating percentage is given below, p e r c e n t a g e = a c t u a l v a l u e T o t a l v a l u e × 100 From the above table total value is 127. To calculate the percentage of students in each category during Year 1 is given below, 2015 Percentage of Freshmen Enrolled 15 127 × 100 = 0.1181 × 100 = 11.81 % Percentage of Sophomores Enrolled 18 127 × 100 = 0.1417 × 100 = 14.17 % Percentage of Juniors Enrolled 21 127 × 100 = 0.1654 × 100 = 16.54 % Percentage of Seniors Enrolled 73 127 × 100 = 0.5748 × 100 = 57.48 % So, the percentage of students in each category during Year 1 is given below, 2015 Percentage of Freshmen Enrolled 11.81% Percentage of Sophomores Enrolled 14.17% Percentage of Juniors Enrolled 16.54% Percentage of Seniors Enrolled 57.48% Procedure: If the theoretical probabilities for the various outcomes are all same, the null and alternative hypotheses for chi-square test for goodness of fit are as follows. H 0 : p 1 = p 2 = ... = p k H a : There is some difference amongst the probabilities
