Answer:
1.) What is the difference between the proportion of women with high blood pressure who use oral contraceptive and those who don't?
2.) P1 - P2
3.)
Let P` = population statistic
P1` - P2`
Step-by-step explanation:

What is the difference between the proportion of women with high blood pressure who use oral contraceptive and those who don't?
2.) P1 - P2
P1 = All women who have high blood pressure and use oral contraceptive
P2 = All women who high blood pressure who don't use oral contraceptive
3.)
P1` - P2` ; (0.15 - 0.10)
P1` = women in the sample (900) who have high blood pressure and use oral contraceptive
P2` = women in the sample (900) who high blood pressure who don't use oral contraceptive
