A summary conclusion to the findings of this study is given below with several key words omitted. Your task is to fill in the missing words, using the list of terms below the summary. Note that some of the words in this list are not part of the summary. According to the Pew Research Center, it is estimated that 64% of the ______ of all US adults said that completely made-up news has caused a great deal of confusion about the basic facts of current events. This value of 64% is a ______ used to estimate the ______ in this study, namely the true ______ of US adults who felt this way, denoted by p. Since this is a sufficiently large ______, the ______ of p is approximately ______ with ______ p and standard deviation Squareroot pq/n according to the ______. Based on this result, a confidence interval for the true proportion p with ______ 90% is given by (0.615, 0.665). This interval has a ______ of 0.025. Because all of the values in this interval are greater than 50%, we can say that the difference between the true proportion p and 50% is ______ and conclude that a majority of US adults feel that "completely made-up news has caused a great deal of confusion about the basic facts of current events."
