O 1614 619 449

Explanation / Answer

we have to find the odds ratio of a female compared to a male for answering Yes compared with No

we know that the formula for the odds ratio is (a*d)/(b*c)

from the table, we have a = 146,b = 325, c = 219 and d = 302

setting the values in the above formula,we get

odds ratio = (146*302)/(325*219) = 44092/71175 = 0.619

so, odds ratio of a female compared to a male for answering Yes compared with No is 0.619

option B is correct
