A researcher has computed two significant Pearson r values from
  independent random samples. Sample A, 171 subjects, produced an r of .75 and
  Sample B, 175 subjects, produced an r of .60.
 
  Do the two sample correlations
  represent a common population correlation?
 
 
 What will be an ideal response?
