Answer:
Consider the following explanations
Step-by-step explanation:
a. The whole argument is based on the controlling of different factors such as age, education and occupation among males and females. Now, this is very subjective how they have controlled occupation. For e.g. – Which all occupation they have considered for as stressful job, which all jobs they have considered as physical tiring jobs. Working in a refinery may be physical tiring job but then working in IT Company can also be tiring.
Therefore since there are lot of factors at play apart the one considered to calculate ratio’s we can say that these differential percentage points can always be more than or less than of what presented in question.
b. The same logic has to be applied to (b) as well. When we say that discrimination account for less than 8 percent of differential we implied to say that occupation nature may have more than 12 percent of differential. Now, if you use above logic and applied from occupation point of view.
