Subject:      STAT questions???

Hi all,
I've some Statistical questions in accordence with implemented SAS/IML
programming.
 
1. How can a correlation coefficient of 0.45 be statistically
   significant with producing a correlation matrix for 10 variables and
   each variable within 10000 cases(row)???
 
2. What's the major difference between case-wise(list-wise) deletion
   and pair-wise missing data deletion and why a correlation matrix
   default method of missing data is case-wise and a t-test(fot
   independent samples) default method of missing data deletion is
   pair-wise???
 
Thanks in advance.
