Explanation / Answer

a)
the total number is
18+46+125+1165 = 1354

b)

The 2 study groups are
Exposure + = 18+46
Exposure - = 125+1165

c)
Total with disease = 18+125
exposed with disease = 18
so percent is 0.1258 = 12.58%

d)
total without disease = 46+1165
exposed = 46
= 46/(46+1165)
= 0.03 about 3%
