In a national survey of 2013 adults, 1283 indicated that they believe rudeness is a more serious problem than in years past. Does this indicate that more than 3/4 of American adults believe rudeness is a worsening problem? State the alternative hypothesis.

• H_a: p > .75, where p is the true proportion of Americans who believe rudeness is worsening.

• H_a: p = .75, where p is the true proportion of Americans who believe rudeness is worsening.

• H_a: p <.75, where p is the true proportion of Americans who believe rudeness is worsening.
