In a previous nationwide poll of a large country, 45% 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, 1199 adults with children under the age of 18 were selected at random and 515 of the 1199 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 = 0.05 significance level. ... Assume that the population is large and the sample is obtained randomly. Because npo (1- Po) 10 %3D and the sample size is 5% of the population size, the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

In a previous nationwide poll of a large country, 45% 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, 1199 adults with
children under the age of 18 were selected at random and 515 of the 1199 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 = 0.05 significance
level.
