Content-Type: multipart/alternative;

Good morning. This is probably a basic question but can't find anything on it. I'm conducting a t-test on my data and want to look at the one-tailed probability. In SPSS, the default is two-tailed. How can I change it two one-tailed? If I'm using 95%, do I split it to 47.5%? Thanks

T-TEST PAIRS=preentitle prejust WITH postentitle postjust (PAIRED)
  /CRITERIA=CI(.95)
