natima [27]

Answer:

Kindly check explanation

Step-by-step explanation:

The prevalence per 1000 among the exposed :

Total number of diseases among those exposed = 60 + 238 = 298

Prevalence per 1000 among the exposed :

(298 / 9000) * 1000 = 33.11

Prevalence per 1000 among the non exposed :

((90 - 60) + (268 - 238)) / 3000

(60 / 3000) * 1000 = 20

Incidence rate per 1000 among the exposed :

238 / 5940 * 1000

0.0400673 * 1000 = 40.07

Incidence rate per 1000 among the unexposed :

((90 - 30) / (3000-30)) * 1000

(60/2970) * 1000 = 20.2
