Question: In May 2009, a GFK Roper poll asked Americans about their preferences about attending a wedding based on the food being served, given a set of choices. Of the respondents, 15.46% said that they would prefer to go to a wedding that serves champagne and caviar, 58.76% would prefer a wedding that serves wine and chicken breasts, 20.62% would like to go to a wedding that serves beer and pigs in a blanket (miniature hot dogs wrapped in crescent rolls), and 5.15% were not able to choose. Assume that these percentages were true for the population of Americans at the time of the poll. Suppose that a recent poll asked the same question of 600 randomly selected Americans, which produced the following results.
Response Champagne and caviar Wine and chicken breasts Beer and pigs in a blanket Not Sure
Frequency 104 294 184 18
Test at the 5% significance level whether the distribution of responses for the recent sample differs from that of May 2009.
