A new study brings new attention to the phenomenon of unidentified flying objects. The study reports that about two-thirds of Americans (65% to be exact) say that they believe that intelligent life exists on other planets. Are older Americans (over 50 years old) less likely to believe that intelligent life exists on other plants? Based on a random sample of 280 older American adults, 60% say intelligent life exists on other planets. Identify the null and alternative hypotheses. The following multiple-choice options contain math elements, so you may need to read them in your screen reader's "reading" or "browse" mode instead of "forms" or "focus" mode. Choice 1 of 6: H 0 : = 0.65 H 0 :=0.65 and H a : < 0.60 H a :<0.60 Choice 2 of 6: H 0 : = 0.65 H 0 :=0.65 and H a : < 0.65 H a :<0.65 Choice 3 of 6: H 0 : = 0.60 H 0 :=0.60 and H a : < 0.60 H a :<0.60 Choice 4 of 6: H 0 : ^ = 0.65 H 0 : ^ =0.65 and
