Question: Free speech for racists? The General Social Survey (GSS) asked this question: “Consider a person who believes that Blacks are genetically inferior. If such a person wanted to make a speech in your community claiming that Blacks are inferior, should he be allowed to speak, or not?” Here are the responses, broken down by the race of the respondent:

a) Because the GSS is essentially an SRS of all adults, we can combine the races in these data and give a 99% confidence interval for the proportion of all adults who would allow a racist to speak. Do this.

b) Find the column percents and use them to compare the attitudes of the three racial groups. How significant are the differences found in the sample?
