University of California Los Angeles Pew Research Center Stats Questions Paper

Last year, the Pew Research Center asked a random selection of Americans questions about the race relations in the US. Two of the questions they asked were:

• Would you say President Trump has…
  1 Made progress toward improving race relations
  2 Tried but failed to make progress toward improving race relations
  3 Not addressed race relations
  4 Made race relations worse
• When it comes to giving black people equal rights with whites, do you think our country has…
  1 Gone too far
  2 Not gone far enough
  3 Been about right

The results of crosstabulating responses is below.

Q1:Create a table of expected results based on an assumption of independence. You can create this on a spreadsheet and just cut and paste it into the response box for this question.

Q2:Use the table of observed results and the table of expected results you just calculated to create a table of chi-square contributions.

Q3:What is the total ??2 value you calculated?

Q4:How many degrees of freedom are there for this ??2 result?

Q5:If I set my ?? at 0.001, the p value you got is low enough to reject ??0H0.
