A random sample of 500 US adults is questioned regarding their political affiliation and opinion on a tax reform bill. The results of this survey are summarized in the following contingency table:

Favor Indifferent Oppose Total
Democrat 138 83 64 285
Republican 64 67 84 215
Total 202 150 148 500

a. Write down your null hypothesis and alternative hypothesis to test the claim that there is no association between political affiliation and tax reform opinion. Use the Chi-square test for independence.
b. Determine the critical region for this test (where you would reject the null hypothesis) for α = 0.02.
c. Use the Chi-Square test for independence to determine if political affiliation and tax reform opinion are independent of each other. What conclusion do you reach (is there an association or not)?
