Use the following information for questions:
In a random sample of 50 men, 40% said they preferred to walk up stairs rather than take the elevator. In a random sample of 40 women, 50% said they preferred the stairs. The difference between the two sample proportions (men - women) is to be calculated.
-Which of the following choices correctly denotes the difference between the two sample proportions that is to be calculated?
A) $ p_1 $ - $ p_2 $ = 0.10
B) $ \hat{p_1} $ - $ \hat{p_2} $ = 0.10
C) $ p_1 $ - $ p_2 $ = -0.10
D) $ \hat{p_1} $ - $ \hat{p_2} $ = -0.10

The sample proportion for men ($ \hat{p_1} $) is 0.40 and for women ($ \hat{p_2} $) is 0.50. The difference is $ \hat{p_1} - \hat{p_2} = 0.40 - 0.50 = -0.10 $.
