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 to use military force?" Of the 1,510 adult Americans surveyed, 1,090 stated the United States made the right decision. In 2008, the organization asked the same question of 1,510 adult Americans and found that 580 believed the United States made the right decision. Construct and interpret a 90% confidence interval for the difference between the two population proportions, P2003 - P2008. The lower bound of a 90% confidence interval is [ ]. (Round to three decimal places as needed.)
