[Statistics] How do you solve this?

A random survey of 705 elderly men, aged 70 and more, was taken and 14.6% were found to have Type 2 diabetes. At the same time, a random survey of 688 elderly women, aged 70 and more, was taken and 9.1% of the women were found to have Type 2 diabetes. By the 95% confidence interval for the difference between the proportion of diabetic men and diabetic women, we can conclude that A: With 95% confidence, we have evidence to indicate that there is a difference between the proportion of diabetic men and diabetic women. B: With 95% confidence, we have NO evidence to indicate that there is a difference between the proportion of diabetic men and diabetic women. B O A
