A polling agency wants to compare support for the president's foreign policies between men and women. They surveyed 2500 U.S. citizens and found a 95% confidence interval for the difference in proportions between men and women who support the president's foreign policies as (-0.05 to -0.025) where population 1 is men and population 2 is women. Select the correct interpretation of this result.
◦ The interval estimates that p₁ – p₂ < 0 which shows that men are more likely than women to support with the president's foreign policies.
◦ The interval does not contain 0, which shows that there is no significant difference in the proportions between men and women.
◦ The number surveyed should be increased to increase the accuracy of the confidence interval.
◦ The interval estimates that p₁ – p₂ < 0 which shows that women are more likely than men to support with the president's foreign policies.
