Transcribed Image Text:9. In a previous poll, 47% 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, 497 of 1106 adults 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 a = 0.01 significance level.
