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 null hypothesis. Ho: p>.75, where p is the true proportion of Americans who believe rudeness is worsening. Ho: p<.75, where p is the true proportion of Americans who believe rudeness is worsening. Ho: p =.75, where p is the true proportion of Americans who believe rudeness is worsening.
