The function TTEST on Excel... is the output a T-value, or is it a P-value? I am trying to analyze data with this test of significance, & I am unsure how to interpret the output of the TTEST function on excel. Thanks.

It's a probability, expressed as a fraction of 1.

Some information that may help:
