In an independent random sample of 100 women, 37 stated that they were in favour of increasing the income tax rate on individuals who earn more than 50,000 per year. A confidence interval for the difference between the men's and women's proportions is estimated and it ranges from 0.03 to 0.23.

B. Approximately what confidence level is associated with this confidence interval? (3 points)

C. Provide an interpretation of the reported interval. (2 points)

D. Zero is not contained within the confidence interval, what does this tell you about the result of a hypothesis test concerning the difference in proportions? (3 points)
