Splitting on alternate yields:
  (no yes)
  (((yes 3) (no 3)) ((no 3) (yes 3)))
The information on this split is: 
  (1. 1.)
Splitting on bar yields:
  (yes no)
  (((no 3) (yes 3)) ((yes 3) (no 3)))
The information on this split is: 
  (1. 1.)
Splitting on fri yields:
  (yes no)
  (((no 3) (yes 2)) ((yes 4) (no 3)))
The information on this split is:

Checking statistical significance...
Examining split for value "some"
There are 4 examples in this split.
For the classification no, 2. are expected.  (A fraction of .5)
There were actually 0 for a difference of -2.
This contributes 2. to Q.
For the classification yes, 2. are expected.  (A fraction of .5)
There were actually 4. for a difference of 2.
This contributes 2. to Q.
Examining split for value "full"
There are 6 examples in this split.
For the classification no, 3. are expected.  (A fraction of .5)
There were actually 4. for a difference of 1.
This contributes .33 to Q.
For the classification yes, 3. are expected.  (A fraction of .5)
There were actually 2. for a difference of -1.
This contributes .33 to Q.
Examining split for value "none"
There are 2 examples in this split.
For the classification no, 1. are expected.  (A fraction of .5)
There were actually 2. for a difference of 1.
This contributes 1. to Q.
For the classification yes, 1. are expected.  (A fraction of .5)
There were actually 0 for a difference of -1.
This contributes 1. to Q.
Evaluating statistical significance with dof=2 and Q=6.67
Probability value is .0356739933472524
==> NOT statistically significant, i.e. the theory that this attribute
    is irrelevant is deemed to be TRUE (probability > .001)
