Prior to a set of compensation policy changes at a company 29% of the employees surveyed said that they liked their job very much, 49% said that they liked their job moderately, and the remaining employees said that they were dissatisfied with their job. Now, in a survey of 206 employees, 51 said they liked their job very much, 102 said that they liked their job moderately, and the remaining employees said that they were dissatisfied with their job. When testing (at the 5% level of significance) whether the proportions have changed, what is the test statistic?
