 True

 False

QUESTION 10

1. Incidence among the exposed = Etiologic cases + background incidence.

 True

 False

QUESTION 11

1. The incidence in the exposed is calculated by:

a/(a+b)
b/ (a+b)

 False

QUESTION 13

subtraction, division
division, addition
addition, division

 True

 False

QUESTION 15

 True

 False

QUESTION 17

1. 200 new cases of HPV were diagnosed in the 1000 college women who got PAP smears at WKU last year. Of those, 120 had five or more sexual partners since becoming sexually active, as compared to 360 who did not have HPV.

Calculate and interpret RR, AR, AP, PAR, and PAR%.  Please show your calculations.
