A) $\mathrm { H } _ { \mathrm { a } }$ : $\mathrm { p } _ { \text {women } } < \mathrm { p } _ { \text {men } }$
B) $\mathrm { H } _ { \mathrm { a } } : \mathrm { p } = 0$
C) $\mathrm { H } _ { \mathrm { a } } : \mathrm { p } _ { \text {women } } > \mathrm { p } _ { \text {men } }$
D) $\mathrm { H } _ { \mathrm { a } }$ : $\mathrm { p } _ { \text {women } } \neq \mathrm { p } _ { \text {men } }$
