Question: Issues, priorities, and politics in an election year. In July 2008, an NBC News/Wall Street Journal poll asked a sample of Americans to state which issue (taken from a list) should be the top priority for the U.S. federal government. The following table lists the top three priorities cited most frequently according to those listed at PollingReport.com. If we expect to observe equal frequencies, then compute a chi-square goodness-of-fit test at a .05 level of significance. Decide whether to retain or reject the null hypothesis.

Job Creation/Economic Growth             Energy and the Cost of Gas              The War in Iraq

                231                                              201                                         161
