In a Pew Research Center poll conducted December 3–8, 2013, American adults age 18 and older were asked if Christmas is more a religious or a cultural holiday for them. Of the respondents, 51% said Christmas is a religious holiday for them, 32% said it is a cultural holiday, and 17% gave other answers (www.pewforum.org). Assume that these results are true for the 2013 population of adults. Recently, a random sample of 1200 American adults age 18 and older was taken, and these adults were asked the same question. Their responses are presented in the following table.

Test at a 2.5% significance level whether the distribution of recent opinions is significantly different from that of the 2013 opinions.
