In a previous poll, 43% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 1124 adults with children under the age of 18 were selected at random, and 460 of those 1124 adults reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased? Use the a=0.1 significance level. 10 and the sample size is greater than 5% of the population size, and the adults in the sample were selected at random, all of satisfied. Because npo (1-Po)= the requirements for testing the hypothesis (Round to one decimal place as needed.)
