In 2013, the Supreme Court of the United States ruled on a California law that banned same-sex marriage. An important element of that decision was public opinion. In March, Public Policy Polling conducted a survey of Florida voters and asked each to identify themselves as either: 1. Democrat, 2. Republican, or 3. Independent, and to choose one of the following:

1. Gay couples should be allowed to marry legally.

2. Gay couples should be allowed to form civil unions but not marry.

3. There should be no legal recognition of a gay couple’s relationship.

The results were recorded. Is there sufficient evidence to infer that the three political persuasions differ?
