V because there is 'V a 0,050 absolute difference between the probability of a true response and the probability ofa negative test result, In a survey of consumers aged 12 and older, respondents were asked how many cell phones were In use by the household. (No two respondents were from the same household.) Among the respondents. 204 answered \"none," 237 said "one,\" 356 said "two," 147 said "three," and 129 responded with tour or more. A survey respondent is selected at random Find the probability that his/her household has four or more cell phones in use Is it unlikely for a household to have Tour or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to U 05. Pttour or more cell phones): (Round to three decimal places as needed.) Is it unlikely for a household to have four or more cell phones in use? O A. No, because the probability ofa respondent with touror more cell phones in use is less than or equal to 0 05 O E. Yes. because the probability ota respondent with touror more cell phones in use is less than or equal to O 05. O C. Yes. because the probability of a respondent with tour or more cell phones in use is greater than 0.05. O D.
