Q3. Wilcoxon Signed Rank Test for matched-pair data from two dependent samples. The California Community Colleges Chancellor's Office publishes enrollment data for each of its community colleges. The table on the right contains the number of students enrolled in the Spring 2013 and the Spring 2014 semesters at a random sample of six community colleges in California. We are interested in testing whether the median number of enrolled students has declined from 2013 to 2014. That is, we are interested in testing whether the population median of the differences (2014 - 2013) is less than zero. Perform the test using a 5% significance level.
