d) explain how it can happen that mountain view appears to favor males when this is not true within each of the professional schools

Explanation / Answer

percent of male applicants admitted = (No. of male applicants/Total no. of male applicants)*100

= (490)/(490 + 310) = 61.25

percent of female applicants admitted = (No. of female applicants/Total no. of female applicants)*100

= 400/700 * 100 = 57.14

-------------------------------------------

b)

percent of male applicants admitted by the business school = 400/710 * 100 = 56.34

percent of male applicants admitted by the law school = 90/200 = 45

-------------------------------------------------------

c)

percent of female applicants admitted by the business school = 200/300 = 66.67

percent of female applicants admitted by law school = 200/400 = 50

---------------------------------------------------

d) It may happen that some of the male candidates have applied for both Business and law simultaneously.

Number of such applications = 310 + 110 - 310 = 110.
