Why or why not? 5) In the chi-square test- is there a statistically significant relationship between South and Collective Bargaining? 6) Looking at the Difference in Means (t-test) Table, if my hypothesis is that cities that have a mayor / council form of government have higher average spending levels than cities that do not have this form of government- did I find for my hypothesis?
