If we have the possibility of different numbers of subjects in each of two groups, we will maximize our power if
 
  a. we put most of the subjects in the group we care most about.
  b. we put most of the subjects in the group we care least about.
  c. we equalize the number of subjects in the two groups.
  d. it doesn't make any difference so long as we maximize the total number of subjects overall.

Question 2

If we use the standard approach to solve for the necessary sample size so that we have power = .75 in a two-sample t test, the value of N that we will obtain from the tables is
 
  a. the number of subjects we will need in each group.
  b. the number of subjects we will need overall.
  c. the number of groups we will need to run.
  d. the number of subjects that we actually have available.
