![Most cases of cervical cancer are linked to a few strains of the human papilloma virus (HPV). The
pharmaceutical company Merck developed a vaccine (Gardisil) against these HPV strains. Worldwide
clinical trials followed young women after vaccination or administration of placebo for two to four years
for signs of HPV-caused cervical cancer. Based on a sample of 100 women in the Gardisil group, 26%
developed cervical cancer, and based on a sample of 100 women in the placebo group, 32% developed
cervical cancer.
Test the claim that the proportion of women who developed cervical cancer in the Gardisil group is less
than the proportion of women who developed cervical cancer in the placebo group at a = 0.05. Round
your answers to three decimal places, and round any interim calculations to four decimal places.
Fill in the hypotheses below where p₁ denotes the proportion of women who developed cervical cancer in
the Gardisil group and p2 denotes the proportion of women who developed cervical cancer in the placebo
group.
