Suppose that, in a more recent poll, 497 of 1106 adults with children under the age of 18 reported that their familyate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under theage of 18 who eat dinner together seven nights a week has decreased?

Hi! Thank you for the question as per the honor code, we’ll answer the first question since the…

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux.
