In a previous poll, 42% 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, of 1060 adults with children under the age of 18 reported that their family ate dinner together seven nights a week.dinner together seven nights a week. Suppose that, in a more recent poll, 423 of 1060adults with children under the age of 18 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 α=0.01 significance level. (a) What are the null and alternative hypotheses? (b) H0 versus H1 (c) Find the test statistic, z0. (d) Find the P-value. 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?
