In 2003, an organization surveyed 1,500 adultAmericans and asked about a certain war, "Do you believe the United States made the right or wrong decision to use military force?" Of the 1,500 adultAmericans surveyed, 1,086 stated the United States made the right decision. In 2008, the organization asked the same question of 1,500 adult Americans and found that 570 believed the United States made the right decision. Construct and interpret a 90% condence interval for the difference between the two population proportions, p2003 - P2008- The lower bound of a 90% condence interval is D. (Round to three decimal places as needed.) Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a random sample of males and females, the following question: "Are you annoyed by people who repeatedly check their mobile phones while having an in-person conversation?" Among the 527 males surveyed, 178 responded "Yes"; among the 559 females surveyed, 208 responded "Yes." Does the evidence suggest a higher proportion of females are annoyed by this behavior? Complete parts (a) through (9) below. (a) Determine the sample proportion for each sample. The proportions of the females and males who took the survey who are annoyed by the behavior in question are D and B, respectively. (Round to four decimal places as needed.) A survey asked, "How many tattoos do you currently have on your body?" Of the 1243 males surveyed, 178 responded that they had at least one tattoo. Of the 1021 females surveyed, 129 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let p, represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p1 - P2. The lower bound is The upper bound is (Round to three decimal places as needed.)Researchers wondered if there was a difference between males and females in regard to some common annoyances.

Of the 1100 adults surveyed, 352 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 330 indicated that they were total abstainers. Complete parts (a) and (b) below. (a) Determine the sample proportion for each sample. The proportions of the adults who took the 1946 survey and the recent survey who were total abstainers are El and B respectively. (Round to three decimal places as needed.)
