In Exercises 7-5, 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).

1. Biodiversity Identify the null and alternative hypotheses resulting from the claim that for the people who were aware of the statement, the proportion of women is equal to the proportion of men.

5. Biodiversity Assume that a P-value of 0.1 is obtained when testing the claim given in Exercise 1 “Biodiversity.” What should be concluded about the null hypothesis? What should be the final conclusion?
