Question: A 2008 online survey by WSOC Channel 9 in Charlotte, North Carolina, asked people to choose their favorite Christmas song from a list of five choices. The following table shows the percentage of people who preferred each of the five songs.
Suppose that these percentages are true for the 2008 population of U.S. adults. Suppose that recently 600 randomly selected U.S. adults were asked the same question, and the following table shows the numbers of adults who preferred each of these five songs.
Test at the 2.5% significance level whether the distribution of results in the recent survey differs from the 2008 distribution reported by WSOC.
