Those who consented were first examined for the presence of precancerous or cells, using the pap smear test, and were only enrolled to participate if they had no sign of cervical cancer. The study took 20 years of two (2) yearly examinations. Note-well: Do not round off the numbers. For an example 0.987 should not be written as 0.99. The final answer should be up to two decimal places. Numbers should be separated by a full stop i.e., 0.98 (do not use a comma 0,98) Oral contraceptives Cervical cancer Total Yes No Yes 600 100 700 No 200 100 300 Total 800 200 1000 1.
