The sample data show a disparity between "average number of females reported by heterosexual males" and "average number of males reported by heterosexual females."When performing a test of statistical significance about heterosexuals' self-reported "number of partners of the opposite sex", what would the null hypothesis be?

A)Heterosexual men exaggerate their self-reported number of female sexual partners

B)Heterosexual women under-report their self-reported number of male sexual partners

C)Both heterosexual men and heterosexual women accurately report their number of partners, and the difference in sample averages is due to random sampling error

D)The average number of female partners reported by heterosexual males is greater than the average number of male partners reported by heterosexual females, but it is not clear why

E)Statements A), B) and D) could all be statements of the null hypothesis

Which is the most appropriate mathematical statement of the null hypothesis?Letm_mbe the population average number of female partners reported by men, letm_fbe the population average number of male partners reported by women, and lets_mands_fbe the population standard deviations of reported number of partners.

A)Men and women are telling the truth, andm_m=m_fands_m=s_f

B)Men and women are telling the truth, andm_m=m_f, buts_mands_fmight differ

C)Men and/or women lie, som_m>m_f, buts_mands_fare equal

D)Men and/or women lie, som_m>m_f, ands_mands_fmight not be equal

E)Men and/or women lie, som_m>m_f, ands_mands_fmust not be equal
