Regression? Chi-Square? ANOVA?

A survey concerning national health care was conducted by a nonprofit thinktank.  Based on the data in the attached Table, determine whether there are regional preferences for type of health care.  What are the managerial implications of your findings?

I have no idea how to determine that.

I am supposed to use one or more of the following techniques (and we are instructed to always use 95% confidence level, unless the problem states otherwise):

-Confidence intervals and hypothesis testing
-Decision trees (and their use in solving managerial problems),
-Critical fractile analysis (and its use in determining optimal demand levels),
-Analysis of variance/ANOVA (and its use in understanding differences between group means),
-Chi-square (cross tabs/contingency table) analysis (and its use in determining differences between group proportions),
-Regression, single and multiple (and its use in understanding relationships between dependent and independent (explanatory) variables), and
-Optimization modeling (and its use in determining the best solution given a set of constraint).

I do not know how to do this.  Help!!
