a) The section describes the distribution for a difference between samples taken from the two distinct groups.  The given situation compares the proportion of students who use Windows-based PC to the proportion who use a Mac. That is, two proportions drawn from the same group is compared here. Thus, the methods of this section do not apply to this type of difference in proportions.  b) The section describes the distribution for a difference between samples taken from the two distinct groups.  The given situation compares the proportion of students who study abroad between those attending public universities and those at private universities. That is, two proportions drawn from from the different groups are compared here. Thus, the methods of this section apply to the given situation.  c) The section describes the distribution for a difference between samples taken from the two distinct groups.  The given situation compares the proportion of in-state students at a university to the proportion from outside the state. That is, two proportions drawn from the same group are compared here. Thus, the methods of this section do not apply to the given situation.  d) The section describes the distribution for a difference between samples taken from the two distinct groups.  The given situation compares the proportion of in-state students who get financial aid to the proportion from out-of-state students who get financial aid. That is, two proportions drawn from the different groups are compared here. Thus, the methods of this section apply to the given situation.
