103. 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?"

In 2008, the organization asked the same question of 1,500 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, p2003p2008.
