Explanation / Answer

(a) This is a random sampling where there is no relation between the men and women. Hence these are independent samples.

(b) Here we want to know if couples have different mean salaries. Here a couples (a man and a women) salaries would be uniquely matched, hence they would be dependant, i.e only if both are working can we take that as a sample data. Hence this case is a case of paired (dependent) samples.
