In 2003, an organization surveyed 1,510 adult Americans and asked about a certain war, "Do you believe the United States made the right or wrong decision t use military force?" Of the 1,510 adult Americans surveyed, 1,085 stated the United States made the right decision. In 2008, the organization asked the same question of 1,510 adult Americans and found that 570 believed the United States made the right decision. Construct and interpret a 90% confidence interval fo the difference between the two population proportions, P2003 - P2008.

In 2003, an organization surveyed 1,500 adult Americans 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 adult Americans surveyed, 1,085 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.
