Question 770048: A researcher is interested in determining whether men's and women's attitudes on the environment differ. To do so 100 men and 100 women were randomly sampled and asked: "Do you think the environment is a major concern currently?" Of those sampled, 67 women and 53 men responded that they believed it is. Suppose a 97% confidence interval for the study was (0.02, 0.26). You may assume sample 1 corresponds to women and sample 2 corresponds to men. You may also assume that all assumptions and checks have been verified.
Based on the interval given, choose the most appropriate portion below from the conclusion for the confidence interval.

a) We are 97 % confident that there is no difference between the corresponding true proportions of women who believe the environment is a major concern currently and the true proportion of men who believe the environment is a major concern currently.
b) We are 97 % confident that the true proportion of women who believe the environment is a major concern currently is greater than the true proportion of men who believe the environment is a major concern currently.
c) We are 97 % confident that the true proportion of women who believe the environment is a major concern currently is smaller than the true proportion of men who believe the environment is a major concern currently.

d) Can’t answer this question based on the information given.

e) None of the above conclusions are correct.
