A poll found that 38% of male voters and 46% of female voters support a particular candidate. To test whether this candidate has equal levels of support between male and female voters, the null hypothesis should be

a) . H0 : pmale =pfemale
b) . H0 : pmale =50 % , H0 : pfemale= 50 %
c) . H0 : pmale =38 % , H0 : pfemale= 46 %
d) H0 : pmale <pfemale .
