The number of women can be represented by the equation w = m+4 / 10.
What is the conditional ratio?
In order to test for conditionalindependence of two variables given the third variable, we use conditional odds ratios, which are odds ratios between two variables for fixed levels of the third variable.
The number of men = m,
The number of women = w,
We have given,
the number of men in a class is 4 less than ten times the number of women.
It means m = 10w -4
so,
m+4 = 10w
w = m+4 / 10
Hence, the number of women can be represented by the equation w = m+4 / 10.
