using a calculator need p value on a r tailed test if the n=9 and the t is 3.204
It would help if you proofread your questions before you posted them.
What is an "r tailed test"?
I don't use a calculator. I look it up on a "t table" in the back of my statistics text.
df = n-1 = 8
For t = 3.204 with 8 df, .05 > p > .01
