The American Press institute report that almost 70% of all American adults use a computer to gain access to news. Suppose you suspect that the proportion of American adults under 30 years old who use a computer to gain access to news exceeds the proportion of Americans at least 30 years old who use a computer to gain access to news. Data for #1 in the first sheet represent responses to the question "Do you use a computer to gain access to news?" given by random samples of American adults under 30 years old and Americans who are at least 30 years old. At a=0.03, conduct a hypothesis test to see if it appears the proportion of american adults under 30 years old who use a computer to gain access to news exceeds the proportion of americans who are at least 30 years old that use a computer to gain access to news.
