Find the values of x₁ (the number of women who were aware of the statement), x₂ (the number of men who were aware of the statement), p̂₁, p̂₂, and the pooled proportion p̅ obtained when testing the claim given in Exercise 1.

Use the following survey results: Randomly selected subjects were asked if they were aware that the Earth has lost half of its wildlife population during the past 50 years. Among 1121 women, 23% said that they were aware. Among 1084 men, 26% said that they were aware (based on data from a Harris poll).
