Finding the p-values of the intercept and slope (regression)

#1
From my simple made-up dataset.

1 12
5 17
7 23
8 9
9 14

I performed a simple regression analysis.

The regression equation is
C2 = 14.1 + 0.150 C1

Predictor Coef StDev T P
Constant 14.100 6.440 2.19 0.116
C1 0.1500 0.9708 0.15 0.887

S = 6.140 R-Sq = 0.8% R-Sq(adj) = 0.0%
-----------------

Now, I'm curious on how the p-value for both the Constant and CI are predicted (0.116 and 0.887), respectively. Is that a way to calculate them by hand without looking up any Statistics table?
