On the most recent tax cut proposal, a random sample of democrats and republicans in the Congress cast their votes as follows: 

Democrats:           Favor = 85       Oppose = 78    Abstain = 37               

Republicans:          Favor = 118     Oppose = 61    Abstain = 25      

Are the opinions on the tax cut proposal independent of party affiliation?  Use a = 0.01
