The cross-table created after the observations made according to the patients' post-treatment conditions with four different treatment techniques is as follows. if α=0.05 is taken, which of the following is true about the independence test of these variables?

                                          treatment technique
patient status            A      B         C      D          total
it got better               25     30       40     23         118

did not recover          25     20      10      27         82

total                           50     50       50     50         200

A)The Chi-Square calculated is = 14.30.

B)The Chi-square table value is=9.35.

C)e13=20.5.

D)The degree of freedom is = 8.
